YTTW RTTZ Fire Resistant Cable Corrugated Copper Metallic Sheath CCC Approved power cables
Production Description:
1. 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.

Y: series Symbol
T: Cooper conductor
T: Copper sheath
W: Inorganic insulation
. 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.
2. According to the BS6378, flexible fireproof cable satisfies the following requirements:
Class A 650 ℃ 3h
Class B 750 ℃ 3h
