Special cable and its kind

Special cable and its kind
The types of wire and cable have become more and more detailed as applications continue to expand. There are professional and special requirements for wire and cable applications in many special areas. Special cable is an increasingly large branch line classification.

So what is Special cable? Special cable is the equivalent of a wide range of ordinary wire and cable, is a series of wire and cable products with a unique structure and special performance, General Special cable has a more rigorous use of the environment, high technical content, use a relatively universal Wire and cable is a little small, high added value and other common features. Special cable often uses new structures, new materials, new design calculation methods and new production processes.
The more used Special cables are fireproof cables, heating cables, and environmental protection cables.

1、Fireproof cable
The common fireproof cables are of type ABHBRP and AFHBR. They have high fire resistance. Under the condition of direct flame burning, they will not cause short circuit and open circuit failure within a certain period of time. Therefore, in the event of a fire, the safe operation of the security system can be guaranteed. , Facilitate fire extinguishing and reduce losses, long-term working temperature -40 °C ~ 500 °C. It is often applied to large-scale construction, petroleum, chemical, metallurgy, electric power and other electrical equipment that requires high fire safety.
2, heating cable
Heating cable is also called heating cable. It is suitable for antifreeze, heat preservation, pour point depressing and heat tracing of long power lines, containers, storage tanks and other high power output. It is suitable for common areas, dangerous areas and corrosion areas. Heating cable can rely on its own energy to emit heat, uniform temperature, will not overheat, safe and reliable, but also has the characteristics of energy conservation, rapid temperature start, easy installation and maintenance, easy automation, no environmental pollution.
3, environmental protection cable
The main characteristic of environmental protection cables is that no harmful substances are produced and discharged during the manufacturing process. The final products do not contain substances that are prohibited by the “ROHS Directive” (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers) that are harmful to the human body. There is no pollution to the environment. It is healthy, environmentally friendly and renewable.
