5.Product features

 Performance of fireproof 
 Outer sheath of HFTGB cable is using non-magnetic metal material made of thread, both to maintain the original soft bend of the cable, but also increase the fire rating, it also ensures that the installation of anti-scratch and the damaged by rats of using at the same time, and also helps heat dissipation when using the cable. HFTGB cable is comparable to regular cable. The materials do not cause fires and cannot be burned or feeding the fire. 
 HFTGB is a real sense of fire proof cable, these materials with over 1300℃high melting points, so HFTGB fire proof cable can also perform normal transmission functions even under 1000℃ of high temperature flame conditions.

    Proprietary technology- Synthetic mineral-insulated flexible materials 
 Synthetic mineral-insulated flexible materials is used silicone rubber as the basis, adding MgO, AlO, vitrified powder etc.. 
 HFTGB--Synthetic mineral-insulated Metal sheath Copper Flexible Fire-proof power Cable enhances the electrical、mechanical and anti-corrosion properties；it can reduce the electrical fault caused by the need of a large number of splices in the installation, solving the problems of easy absorption impact the insulating property for BTTZ cable.

  Flexible 
 The construction of HFTGB cable is similar to regular cable, but it’s flexible as same as the regulars, this is the real flexible. It can be continuously wound on the cable tray in production and smoothly lined in installation. 
 The conductor of the cable adopts the mature strand compression technigue, improving the flexibility on the basis of ensuring the smooth and round of conductor. 
 The insulation adopt synthetic mineral flexible materials, the flexibility is the same as the regular cable. 
 The outer jacket adopt non-magnetic stainless steel material made of thread, and ensuring the bending of the cable.
