Low Smoke Mineral Insulated Cable Flexible BTTZ Series High Temperature Cable
Structure of flexible fireproof cable
1. Cable conductor: it is made up of stranded copper wires, with
favorable flexural property
2. Insulation layer : it adopts high-temperature resistant
inorganic insulating materials
3. Copper sheath: copper materials, through special machining, with
favorable flexural property. used as PE wire.
4. Outer sheath: it is made of plastic materials of low-smoke
non-toxicity, with favorable corrosion protection.
According to national standards, fire-resistant wire and cable:
fire test method characteristic test, According to GB12666. 6 Class
A, burn in fire with flame temperature 950℃ apply voltage of 750V
between phase and phase and between phase and outer sheath it
should be able to withstand for 90min without breakdown.
Class B, bun in fire with flame temperature 750-800 ° C, apply
voltage of 750V between phase and phase and between phase and
sheath it should be able to withstand for 90 min without breakdown.
According to the BS6378, flexible fireproof cable satisfies the
following requirements:
Class A 650 ℃ 3h
Class B 750 ℃ 3h
Class C 950 ℃ 3h
Class S 950 ℃ 20min
Rated Voltage: 0.6/1kV
Rated working voltage: light load 500V, heavy load 750V;
Rated current: single core 25-1800 A; multi-core 16-500A
Insulation resistance: insulation resistance≥ 1000MΩ per km. cable
length less than 100m, then the insulation resistance ≥ 10000 MΩ
Power frequency withstand voltage: apply voltage of 2000V and 2500
V between phase and copper sheath of cables of 500V and 750V
respectively, they should be able to withstand for 15 min without
being broken down.
