1. What is a special cable? What is the difference with ordinary cables?

Special cables are cables that have special uses and can be used on specific occasions. Special cables are a series of products with unique properties and special structures. Compared with ordinary wires and cables with a large quantity and a wide range, special cables have the characteristics of higher technical content, stricter use conditions, smaller batches, and higher added value. Special cables often adopt new structures, new materials, new design calculation methods and new production processes.

Second, the characteristics and classification of special cables

Special cables have special functions due to their special use occasions or specific use conditions, such as high temperature or severe cold resistance, strong acid and alkali resistance, termite resistance, low noise, superconducting, waterproof, soft and wear-resistant, and environmental protection. . So far, special cables are mainly divided into four categories: high temperature resistant wire and cable, special structure and specific purpose wire and cable, functionalized wire and cable, and new green and environmentally friendly wire and cable.

Third, the diversified development direction of special cables

The development direction of special cables is diversified. The military industry has a large demand for light-weight and high-temperature-resistant cables. In terms of construction, fire-resistant and high-temperature resistant wires and cables and low-smoke, halogen-free and environmentally friendly wires and cables can effectively prevent fire and safety accidents. In fields such as medicine and national defense that require small signal measurement, low-inductance and low-noise wires and cables are needed. For oil platforms, deep well survey cables, heating and temperature control cables, and submarine integrated cables are needed. In urban power distribution, substations, power plants and other occasions that need to transmit large currents over short distances, superconducting cables are required. In terms of industrial intelligence, super-flexible, wear-resistant and easy to move drag chain cables are needed. In the application of locomotives and AC motors, frequency conversion cables are required.www.rfcable.com.cn/en
