Flexible Mineral Insulated Fire Resistant Cable--BBTRZ
Comparative advantages of BBTRZ flexible mineral insulated fireproof cables:
1. Electrical properties
Large current-carrying capacity: Under the same conditions, the current-carrying capacity of BBTRZ cable is larger, and the rated current-carrying capacity of its conductor operating temperature of 90°C is basically equivalent to the current-carrying value of BBTZ cable operating temperature of 125°C, which is much higher than other cables.
The material has good insulation. BBTRZ cable uses inorganic non-metallic materials as insulation and sheath, with multi-layer insulation protection structure, which is fireproof and waterproof at the same time, so it has excellent insulation performance. It can be customized in continuous large lengths without intermediate joints, and overcomes the defects of a single core. Grounding is safer. BBTRZ cables use a special ground wire to reduce safety hazards.
3. Energy saving
The BBTRZ cable has large current carrying capacity, low wire calorific value, and the multi-core large-section structure completely offsets the electromagnetic effect. Thermal field, magnetic field and other reactive power losses are much lower than BTTZ and other products.
BBTRZ cables are flexible, so construction is very easy, efficient and reliable. At the same time, the BBTRZ cable can be laid in the same groove as the ordinary cable, which saves space, is easy to maintain, and is suitable for various laying methods.
BBTRZ cable performance advantages and disadvantages:
1. The cable is flexible and easy to install;
2. Anti-overload, anti-external force;
3. Large carrying capacity;
4. Halogen-free, non-toxic;
5. Corrosion-resistant, insect-proof;
6. No need for infinite length of intermediate joints;
7. High temperature resistance;
8. The maximum conductor area of the single-core structure can reach 630mm²;
9. The maximum cross-section of the conductor of the multi-core structure can be 400mm².
