• After sales service: A manufacturer that provides comprehensive after-sales service, such as long-term warranty, quick repair response, and technical support. The operating cost is high, and the product price will also include this part of the cost.

Livestock farming

• Incubation and insulation for chicks: In poultry farming such as chicks and ducklings, strict temperature requirements are imposed during the brooding stage.If the electric heating wire is laid in the chicken coop or under the breeding ground, the temperature can be maintained at around 30 ℃ -35 ℃ through an intelligent temperature control system, providing a suitable temperature environment for chicks and improving their survival rate and health level.

• Keeping warm during farrowing: For sows, ewes, etc. during farrowing, electric heating wires can be installed in the farrowing pen or delivery house. For example, when a sow gives birth, placing a piglet electric heating plate in a corner of the bed and setting the temperature at around 30 ℃ can prevent newborn piglets from being exposed to cold, reduce diseases and deaths caused by low temperatures, and improve the survival rate of piglets.

• Winter heating: In winter, the overall temperature of the breeding farm is low, which affects the growth of poultry and livestock. By installing electric heating wires on the walls, ceilings, or floors of poultry houses, the temperature inside the house can be increased. Taking the cowshed as an example, the temperature inside the shed can be maintained at 10 ℃ -15 ℃, creating a comfortable growth environment for poultry and livestock, reducing energy consumption, and improving breeding efficiency.

1、 The higher the power, the higher the price

• Typically, high-power electric heating wires require the use of more conductive materials and thicker wires, resulting in relatively higher manufacturing costs. For example, high-power electric heating wires may require the use of higher quality alloy materials or more carbon fiber wires to ensure they can withstand larger currents and heating power.

• High power electric heating wires often require more complex production processes and higher technical requirements, which also increase production costs and lead to price increases. For example, stricter quality inspection and control are required during the production process to ensure the safety and stability of the product.

2、 The lower the power, the lower the price may be

• The materials and production processes required for low-power electric heating cable are relatively simple and cost-effective. For example, low-power electric heating wires can use thinner wires and fewer conductive materials, and the production process is relatively easy.

• For some small heating devices or applications with low power requirements, there is a high demand for low-power electric heating wires, and market competition is also fierce, which may result in relatively low prices.

However, it should be noted that the price of electric hotlines is not only determined by the power output, but also influenced by various factors such as material, brand, and quality.

Select high-efficiency heating materials:

• Graphene: It has ultra-high thermal conductivity and carrier mobility, and can quickly convert electrical energy into thermal energy. In low-temperature environments, its excellent electrical properties can rapidly raise the temperature of the heating film, reducing the heating delay caused by low temperatures. For example, the application of graphene heating film in some high-end warm clothing can quickly provide warmth to the human body in cold weather.
• High performance carbon fiber: Not only does it have high heating efficiency, but it can also generate far-infrared radiation that is beneficial to the human body. In low-temperature environments, carbon fiber heating membranes have good stability, and far-infrared radiation can promote blood circulation in the human body, indirectly improving the insulation effect and enhancing overall heating efficiency.

Strengthen insulation measures:

• Add thermal insulation layer: wrap thermal insulation materials around the heating film, such as polystyrene foam, polyurethane foam, etc., to reduce heat loss to the low-temperature environment. For example, when using heating film for underfloor heating, laying insulation board under the heating film can effectively prevent heat from transferring downwards, allowing more heat to stay in the indoor space and improving heating efficiency.
• Improve spatial sealing: For spaces using heating membranes, such as rooms, equipment enclosures, etc., enhance their sealing. Install sealing strips, double-layer glass, etc. to reduce the penetration of cold air and minimize heat loss caused by air convection. In the cold winter, a well sealed room can better maintain the heat generated by the heating film and improve the actual efficiency of its use.

Intelligent temperature control:

• Adopting high-precision temperature controller: Equipped with a high-precision temperature controller, it can more accurately sense temperature changes and adjust the working status of the heating film in a timely manner. In low-temperature environments, the thermostat can accurately control the power output of the heating film based on the slight difference between the set temperature and the actual temperature, avoiding excessive or insufficient operation of the heating film due to inaccurate temperature control and improving heating efficiency.

Adapt to suitable power sources:

• Stable voltage output: For AC powered heating films, select the appropriate power frequency based on their material characteristics and design requirements. The appropriate frequency can make the electronic movement inside the heating film smoother, the current distribution more reasonable, and thus improve the heating efficiency.

1. Raw material costs

• Carbon fiber quality: The quality of carbon fiber is one of the key factors determining its price. High quality carbon fiber has higher strength, better conductivity, and thermal stability. The heating wires produced by well-known carbon fiber brands are relatively expensive because these carbon fibers perform well in terms of raw material purity, uniformity of fiber bundles, etc., ensuring excellent and stable performance of the heating wires.

•  Auxiliary materials: In addition to the carbon fiber body, auxiliary materials such as insulation layer and sheath of the heating wire will also affect the price. High quality insulation materials, such as fluoroplastics (PTFE), polyvinyl chloride (PVC), etc., have good electrical insulation, high temperature resistance, and corrosion resistance, which can improve the safety and service life of heating wires, but the cost is also high. For example, the price of carbon fiber heating wires using high-performance fluoroplastics as insulation layers will be higher than that of ordinary PVC insulated heating wires.

2. Production process

• Manufacturing accuracy: High precision manufacturing processes can ensure consistent performance of carbon fiber heating wires. For example, in the winding and weaving process of carbon fiber filaments, if the technology is advanced and the precision is high, it can make the resistance of the heating wire uniform and the heating efficiency stable. By adopting advanced automated production equipment and precise manufacturing processes, the price of the produced heating wire will correspondingly increase, as these processes can effectively reduce the rate of defective products and improve product quality.

• The complexity of the production process: If the production process involves special processing steps, such as surface modification of carbon fibers, manufacturing of multi-layer composite structures, etc., it will increase production costs and thus affect prices. For example, carbon fiber heating wires that have undergone special surface treatment can enhance the bonding strength between carbon fiber and other materials, improve the overall performance of the heating wire, but this additional treatment process will increase the price.

3. Power and specifications

• Power size: Generally speaking, carbon fiber heating wires with higher power have relatively higher prices. This is because high-power heating wires require the use of more carbon fiber materials, and in the design and manufacturing process, many factors such as heat dissipation and safety need to be considered, resulting in higher requirements for technology and materials. For example, high-power carbon fiber heating wires used for industrial heating (such as those with a power of over 1000W) are more expensive than ordinary household heating wires with lower power (such as 100-500W).

• Length and wire diameter specifications: Carbon fiber heating wires with different length and wire diameter specifications have different prices. A longer heating wire naturally has a higher price, while a thicker wire diameter usually means higher heating efficiency and carrying capacity, and the price will correspondingly increase. For example, a carbon fiber heating wire with a diameter of 6mm will be more expensive than a similar heating wire with a diameter of 3mm.

4. Application areas and market demand

• Market supply and demand relationship: When the demand for far infrared heating cable in the market exceeds the supply, prices often rise; On the contrary, prices may decrease. For example, during the peak season of winter heating demand, the market demand for carbon fiber underfloor heating lines increases significantly. If the supply is relatively tight, the price will rise. In some off-season or emerging application areas where market demand has not yet fully opened up, prices may remain relatively stable or decrease to stimulate market demand.
