HFTGB series of flexible synthetic mineral insulated fireproof cables are made of copper stranded wire as conductor, wrapped with mineral oxygen barrier, extruded with synthetic mineral insulating material, and then covered with synthetic mineral belt, and the outer layer is spirally wrapped with non-magnetic stainless steel belt. Where the metal sheath is specifically required to not be exposed, a low-smoke, halogen-free sheath can be added to the outside.
Basic product parameters:
Conductor: The conductor is a round copper stranded wire.
Insulation: mineral oxygen barrier, then extruded synthetic mineral insulating material
Filling layer: The synthetic mineral belt is covered with a mineral compound.
Sheath: Spiral wrapped with non-magnetic stainless steel belt.
Use: This product is the first in China, and there is no prototype in the world. Compared with the BTTZ series of metal outer sheathed cables, the product maintains ultra-high fire resistance and electrical resistance. It can achieve continuous large length and multi-core cable within 120 mm, which overcomes the shortcomings of too many joints, and stainless steel The mechanical properties and environmental corrosion resistance of the outer sheath are greatly improved.
Special cables
Features: Flexible synthetic mineral insulated fireproof cable adopts a flexible structure to make up for the defects of hard structure, flammability, and toxicity. It also has some advantages that other cables cannot have, such as: fire resistance, large current carrying capacity, and impact voltage resistance , Mechanical damage resistance, halogen-free, non-toxic, explosion-proof, waterproof, anti-rat bite, corrosion resistance, long life, safety, overload resistance, high temperature resistance, heat insulation and low comprehensive cost characteristics, flexible synthetic mineral insulated fireproof cable HFTGB( Y) The process structure of the product is exactly the same as that of the traditional cable. It successfully solves the many shortcomings of the product determined by the production process of the magnesium oxide mineral insulated cable (BTTZ). At the same time, the power and the communication fireproof cable are integrated, so that in the event of a fire Keep communication information unblocked.
product description:
HFTGB cable is the first in China, and there is no prototype in the world. Compared with the BTTZ series of metal outer sheathed cables, the product maintains ultra-high fire resistance and electrical resistance performance. It can achieve continuous large length and multi-core cable within 120mm2, which overcomes the shortcomings of too many joints, and The mechanical properties and environmental corrosion resistance of the stainless steel outer sheath are greatly improved. However, the structure of this product is also complicated, the conductive performance of the stainless steel outer sheath is weak, and it cannot replace the grounding wire like a copper sheath. The overall cost is relatively high among the major categories of mineral cables.
Product performance standards:
1. BS 6387:1994 performance requirements for cables to maintain circuit integrity under flame conditions;
2. Follow the corresponding corporate standards.
Product characteristics:
Voltage level: 0.6/1kV, working voltage is 500V for light load and 1000V for heavy load.
Working environment: The long-term working temperature is 70°C for the sheath; the long-term working temperature of the mineral insulated cable is 105°C where no one can touch it.
Requirements:
1. Installation conditions: It is suitable for the open laying of the ladder frame, and the installation methods such as bridge frame, pipe-through, and burying can also be adopted;
2. Installation process: there are special connectors, please refer to the manufacturer’s “installation instruction manual” for details;
3. Matters needing attention: The bending of the stainless steel metal sheath must be carried out in a reliable way. A single single-core cable is not suitable for laying directly through a metal pipe.
