What Are Special Cables? What Are The Main Types?

- Aug 03, 2020-  

Special cables are cables for specific purposes that are used on specific occasions. They are a series of products with unique properties and special structures. Compared with ordinary cables, they have higher technical content and stricter operating conditions. The most commonly used special cables include fireproof cables, heating cables, and environmental protection cables.

1. Fireproof cable

Common fire-resistant cables are ABHBRP and AFHBR, which have high fire resistance. Under the condition of direct flame burning, there will be no short circuit or open circuit fault within a certain period of time. Therefore, in the event of a fire, the safe operation of the system is guaranteed , Is conducive to extinguishing fire and reducing loss, long-term working temperature is -40℃~500℃. It is often suitable for the connection of electrical equipment in large buildings, petroleum, chemical, metallurgical, electric power and other occasions that require high fire safety.

2. Heating cable

Heat tracing cables are also called heating cables. They are suitable for antifreeze, heat preservation, condensation reduction, and heat tracing for long pipelines, containers, storage tanks and other high-power output. They are suitable for ordinary, dangerous and corrosive areas. The heat tracing cable can generate heat by its own electric energy, the temperature is uniform, will not overheat, safe and reliable, and also has the characteristics of energy saving, fast heating start, easy installation and maintenance, easy automatic management, and no environmental pollution.

3. Environmental protection cable

The main feature of environmentally friendly cables is that no harmful substances are generated or discharged during the manufacturing process. The final product does not contain substances that are banned in the ROHS Directive (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers) that are harmful to humans , There is no pollution to the environment, good for health, good for the environment and renewable processing.
