Description

5-core BTTZ fireproof cable

Technical Field

The utility model relates to a fireproof cable technical field specifically is a 5 core BTTZ fireproof cable.

Background

BTTZ is a cable with mineral (magnesium oxide) as the insulating material. Usually consisting of a copper conductor, mineral insulation, copper sheathing, and no organic material. It has the characteristics of non-combustion, no smoke, no toxicity and fire resistance. The better fire resistance of the BTTZ fireproof cable is one of the excellent characteristics of the mineral insulated cable, so people select the mineral insulated cable and link the cable with fire resistance requirements, and the cable is also commonly called as the fireproof cable.

The cable in the prior art is overheated after being used for a long time, is unfavorable for the service life of the wire and has poor protection function.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a 5 core BTTZ fireproof cable to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a 5 core BTTZ fireproof cable, includes five insulation boards and an insulating tube, five the insulation board evenly sets up in the insulating tube in order to be divided into five cavities, all be equipped with the wire in the cavity, the insulating tube outside is equipped with liquid nitrogen layer, the liquid nitrogen intussuseption is filled with liquid nitrogen slurry, be equipped with five through-holes on the insulating tube, five through-holes are linked together with five cavities respectively to make liquid nitrogen slurry fill and get into the cavity and cool down the fire prevention to the wire, the outside cover on liquid nitrogen layer is equipped with fire-retardant layer, the outside cover on fire-retardant layer is equipped with the waterproof layer, the outside cover of waterproof layer is equipped with the metal level, the.

Further, the flame-retardant layer is a ceramic-synthesized fireproof insulating tape.

Further, the waterproof layer is made of rubber materials.

Further, the outer protecting sleeve is a stainless steel threaded metal protecting sleeve.

Furthermore, the insulating plate and the insulating tube are both made of mica insulating materials.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the cable has the functions of fire prevention, temperature reduction, fire prevention, flame retardance, water prevention, protection and the like from outside to inside through the application of the insulating tube, the liquid nitrogen layer, the flame retardant layer, the waterproof layer, the metal layer and the outer protective sleeve;

2. liquid nitrogen slurry can enter the cavity through the through hole in the liquid nitrogen layer in the cable to cool and prevent fire for the wire, and the service life of the wire is prolonged.
