BTTE is a fire-resistant power cable.
BTTE (or BTLE) is a copper-core, low-smoke, halogen-free sheathed cable insulated with inorganic mineral materials. It is a type of fire-resistant cable. The following is its key information:
1. Structure and Composition
It consists of a copper conductor, an inorganic mineral insulation layer, and a halogen-free sheath, offering high fire resistance.
The outer sheath is made of a low-smoke, non-toxic plastic material with corrosion resistance.
2. Key Features
Fire Resistance: Maintains insulation at high temperatures, operates at high temperatures, and has a high current carrying capacity.
Application Scenarios: Suitable for critical facilities such as fire pump power supply and distribution and emergency generator sets.
Installation Requirements: No preheating is required during installation. The bending radius must meet the requirements of 20 times the cable outer diameter + conductor outer diameter for single-core cables and 15 times the cable outer diameter for multi-core cables.
3. Specifications and Models
The voltage level is 0.6/1kV. Common specifications include single-core (1.5-500mm²) and multi-core (such as 3×120+1×70).
Other similar models include YTTW, BTTW, BTTRZ, etc.
4. Production and Standards
This product complies with standards such as GB/T 2706-2008.
