BTTRZ is a type of mineral insulated cable with a flexible, fire-resistant structure. The manufacturing process for BTTRZ cables is similar to that for BTTZ cables, but the cables are more flexible and flame-retardant, making them convenient and quick to transport, highly flexible, and safer and more reliable to use.
BTTRZ mineral insulated cable, also known as flexible copper-sheathed inorganic mineral insulated fire-resistant cable, is a type of mineral insulated cable with a flexible structure.
Basic parameters of BTTRZ cables include:
Specifications: Number of cores: Single core: 10-630mm²; 2/3/4 core: 2.5-120mm²; 3+1 core: 16-120mm².
Operating temperature: Up to 950°C.
Special Features: Excellent fire resistance, moderate water resistance
Rated Voltage: 0.6/1kV
Installation Conditions: Can be laid openly, no cable tray or conduit required
Service Life: 50-100 years
Product Advantages:
BTTRZ, like other flexible mineral insulated cables, offers advantages such as fire safety performance, load capacity, large cross-sectional area, corrosion resistance, excellent shielding, low smoke and low halogen levels during combustion, safety, reliability, and stability, and a long service life. Compared to BTTZ cables, BTTRZ cables are more convenient and quicker to transport and install.
Differences between BTTZ and BTTRZ cables:
1. BTTZ is a copper core, copper sheathed, magnesium oxide insulated, rigid fire-resistant cable, while BTTRZ is a copper core, inorganic mineral tape-insulated, copper sheathed, flexible fire-resistant cable.
2. BTTRZ cables are flexible mineral insulated cables, unlike BTTZ cables, and BTTZ cables are not as flexible as BTTRZ cables.
3. BTTZ cables are not flame-retardant, while BTTRZ is a flame-retardant copper-core cable.
BTTRZ can replace BTTZ. The former is a flame-retardant copper-core cable for routing, while the latter is not. While the two products share the same manufacturing process, they use different insulation materials. Currently, the former is more commonly used.
