What Is A Special Cable?

What is special wire and cable? Special cable is equivalent to ordinary wire and cable with a large amount and a wide range. It is a series of wire and cable products with unique structure and special performance. Generally, special cables have stricter use environment and technical content. Some common features are higher, the usage is slightly smaller than that of general-purpose wires and cables, and the added value is higher. Special cables often use new structures, new materials, new design calculation methods and new production processes.

Next, what are the types of special wires and cables we introduce?

We usually use heating cables, environmental protection cables, fireproof cables, etc.; we will focus on these three below;

1. Environmental protection wire and cable

The main feature of environmentally friendly cables is that no harmful substances are produced and discharged during the manufacturing process, and the final product does not contain harmful substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers) that are prohibited in the ROHS Directive. Substances that do not pollute the environment, are beneficial to health, the environment and can be recycled.

2. Heating wire and cable

Heating cables are also called heating cables. They are suitable for antifreeze, heat preservation, condensation reduction and heat tracing with high power output such as long pipelines, containers and storage tanks. They are suitable for common areas, dangerous areas and corrosion areas. The heating cable can rely on its own electric energy to generate heat, the temperature is uniform, it will not overheat, it is safe and reliable, it also has the characteristics of saving electric energy, fast heating and starting, easy installation and maintenance, easy automatic management, and no environmental pollution.

3. Fireproof wire and cable

Common fire-resistant cables are ABHBRP and AFHBR types, which have high fire resistance. Under the condition of direct flame burning, short-circuit and open-circuit faults will not occur within a certain period of time. Therefore, in the event of a fire, the safe operation of the system is guaranteed. , is conducive to fire extinguishing and reduce losses, long-term working temperature -40 ℃ ~ 500 ℃. It is often used in the connection of electrical equipment in large buildings, petroleum, chemical industry, metallurgy, electric power and other occasions requiring high fire safety.
