Production Description:

Flexible fireproof cable and copper sheath embossing mineral insulated cable. The cable is a new fireproof cable defects based on modified insulated cables in mineral, it can overcome the disadvantages of mineral insulated cable production is limited by the length of the middle joint installation, avoid appearing in question, has the advantages of the insulation layer is not easy to damp, installation convenience, with the continuous promotion of the product excellent performance, they are increasingly affected by the broad masses of customers, it has been widely used in industrial and civil construction.


The traditional fire-resistant cables of existing national standards cannot guarantee the fire protection requirements of high-rise and super high-rise buildings. Traditional fire-resistant cables can only maintain reliability for 90 minutes under fire conditions, and the smoke emitted during the combustion process affects personnel escape and fire rescue.For this reason ,special effect buildings, first-class buildings and super high-rise buildings should use mineral insulated cables.
