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

Class C 950 ℃ 3h

Class S 950 ℃ 20min

4. Special Characteristics:


1. Fire resistant

Will neither burn or support combustion. Comply with the requirements of IEC 60331 and BS 6387.

2. High operation temperature

Continuous operating temperature up to 250 °C, and for short periods up to approaching the melting point of copper 1083 °C.

3. Inherent flameproof barrier

With a non-flammable sheath the high compacted insulation will resist the transmission of vapors, gases or flames.

4. High mechanical strength

Really robust and can withstand a considerable amount of stresses such as, twisting, bending and flattening.

5. Pliable

Fully annealed and extremely ductile and easily manipulated to follow existing wiring routes and irregular shapes.

6. Non-ageing, Integral earth continuity, Small overall diameter

Waterproof, Corrosion resistant, Radiation resistant, Excellent electric shielding, Easy installation, Long service life
