Structure and Characteristics of Inorganic Insulated Fireproof Cable

Inorganic composite insulated fire-resistant power cable has superior fireproof performance, long production length, good bending performance, and can completely replace BTTZ cable in performance. It is unmatched by traditional mineral insulated cables.

First, the Cable Structure:

1. Stranded conductor.

2. Inorganic composite insulation.

3. Inorganic composite expansion filling.

4. Wrinkle copper tube sheath.

5. Low-smoke halogen-free outer sheath.

Second, the Performance Characteristics:

1 Fire and Fire Resistance is very Good

In order to ensure the normal supply of the cable in the flame, that is, to keep the cable structure stable under fire conditions, in the cable structure design, a coating layer with refractory and expansion properties is added, and the coating layer is in flame condition and volume. Expansion makes the cable insulation structure more stable. Therefore, the cable can continue to supply power in the event of a fire close to the melting point of copper, which is a true fireproof cable.

2 Continuous Production Length, Large Section, Good Bending Performance

Continuous production length is long

The production length of the cable is not limited by the processing technology and production equipment, and fully meets the power supply length. 

The longest can be produced to 2000 meters.

Large cross section

The cable conductor is formed by stranding a plurality of single wires, which greatly increases the flexibility of the conductor, and the stranded conductor has good continuity of production, long processing length, and can reduce the number of joints, and the cross section of the single core cable can be large. Up to 800mm2.
