1kV LSZH Mineral Insulated Wire Multicore Mi Heating Cable
Mineral Insulated Wire is suitable for power transmission under 0.6/1KV voltage, with continuous working temperature of 250 ℃ and power supply for 3 hours at 950-1000 ℃.
Mineral Insulated Wire Features
(1) Fire prevention. BBTRZ cable uses mica tape and extruded composite insulation, using refractory materials
Mortar insulation and fire protection, the new material product can pass the BS 6387 standard C level test under 950℃ flame for 80 minutes, no electrical breakdown; 15 minutes after 15 minutes of water immersion, W650℃ flame, no breakdown, b level test at 950 No breakdown within 15 minutes under flame at ℃.
(2) Flexible. The conductor of the BBTRZ cable is made of copper stranded wire, and the insulation layer is made of mica tape and extruded composite material. Fire-resistant clay is used as heat insulation and fireproof material and halogen-free, low-smoke flame-retardant sheath material. The product is more flexible .
(3) Environmental protection. The burning transmittance of BBTRZ cable exceeds 80% (the standard is 60%), which meets the requirements of low smoke. Since the cable insulation and sheath materials are inorganic compounds, there is no usual PVC material. Therefore, even under fire conditions, no acid gas is emitted, nor halogens are generated.
(4) Security. It can supply power in the flame, start fire-fighting equipment, reduce fire losses, and is particularly reliable for personal safety.
(5) Long service life. Inorganic insulating materials can withstand high temperatures and are not easy to age, and their service life is many times that of organic insulated cables.
