The selection of building indoor wire and cable materials needs to consider many factors, including safety, durability, fire resistance, environmental protection and cost-effectiveness.
1. Cross-linked polyethylene (XLPE)
Heat resistance: XLPE cable has high heat resistance and is suitable for high-power circuits.
Mechanical strength: XLPE cable has excellent mechanical strength and wear resistance.
Environmental stress resistance: XLPE material has good resistance to environmental stress cracking.
2. Rubber (such as ethylene propylene rubber EPR)
Heat resistance: Rubber cable has good heat resistance and is suitable for high temperature environment.
Flexibility: Rubber cable is soft and easy to install and wire.
3. Flame retardant low smoke zero halogen material (LSZH)
Flame retardancy: In the event of a fire, LSZH cables produce less smoke and toxic gases.
Environmental protection: It does not contain halogens and does not produce harmful gases when burned.
4. Shielding material
Anti-interference: Shielded cable can reduce electromagnetic interference and ensure the stability of signal transmission.
When selecting indoor wire and cable materials, you also need to consider the cable's rated voltage, current capacity, laying method (such as pipeline laying, open laying, concealed laying, etc.), ambient temperature, and whether special properties are required (such as wear resistance, corrosion resistance, etc.). In addition, the installation and maintenance of cables also need to comply with relevant building electrical specifications and safety standards.
