In modern industrial, transportation, power and communication systems, wires and cables play a crucial role. According to different application requirements and working environments, there are various types of cables, and their safety, reliability and durability need to be verified through various international testing standards.
LIB offers solutions covering a wide range of cable testing requirements. This article will introduce common cable types, corresponding test standards, and recommend LIB test chamber equipment.
Classification of Cable Types
1. Power Cable
For transmitting and distributing high-power electrical energy and is commonly found in urban underground power grids, power plants, industrial and mining enterprises, etc. Including overhead insulated cables, which are characterized by no outer sheath and are suitable for space-constrained environments.
2. Communication Cables and Optical Cables
For transmitting telephone, data, television, Internet and optical fiber signals, and is the foundation of telecommunications, power and broadcasting systems. The interior of an optical cable is made of glass fiber, while that of a cable is a copper core conductor.
3. Control Cable
Transmits control signals, suitable for automated production lines, robots, etc. It features high-temperature resistance, oil resistance, anti-interference and other properties, and is often used in the control of industrial equipment with voltages of 450/750V and below.
4. Cables for Electrical Equipment
Internal connection of equipment such as motors and transformers, with various specifications and wide application range.
5. Special Cables
Including the following categories:
Fire-resistant cable (NH) : able to operate continuously at a high temperature of 75 to 80℃ for more than 90 minutes.
Flame-retardant cables (ZR) and low smoke zero halogen (WDZ) : used in densely populated areas.
Mining cables, explosion-proof, waterproof, rodent-proof, etc. : Meeting the requirements of corrosion resistance, pressure resistance, wear resistance, etc. in special industrial environments.
