Description

Silicon rubber insulation fireproof control cable

Technical field

The utility model relates to field of cable technology, particularly relates to a kind of silicon rubber insulation fireproof control cable.

Background technology

At present; existing control cable is directly provided with insulating barrier outward at conductor; due to its inner conductor not having refractory protection; therefore when a fire, insulating barrier will be burnt in a short period of time, and conductor exposes in atmosphere; cause short circuit; cause cisco unity malfunction, bring very large loss, need to improve.

Utility model content

The utility model object is exactly the defect in order to make up prior art, provides a kind of silicon rubber insulation fireproof control cable.

The utility model is achieved through the following technical solutions:

A kind of silicon rubber insulation fireproof control cable, include five cores, described core includes earth connection core conductor and surrounding five strands of power wire core conductors of central authorities, described earth connection core conductor and power wire core conductor are all twisted by superfine zinc-plated copper wire and superfine tin-coated copper tow and form, silicone rubber insulation layer and polyimide insulative layer is provided with successively respectively in the outside of earth connection core conductor and power wire core conductor, chlorosulfonated polyethylene protective layer is surrounded by outside core, the tangent placement between two of five cores is coated with plastic film successively in outside, plastic adhesive tape, alkali-free glass fibre packed layer, glass fiber fireprotection layer and the fire-resistant sheath of nanoscale halogen-free anti-flaming polyolefin, fluid sealant is respectively equipped with at the inner and outer wall of glass fiber fireprotection layer.

Described fluid sealant is made up of butyl rubber and carbon black.

The utility model has the advantages that: outside the utility model, be coated with plastic film, plastic adhesive tape, alkali-free glass fibre packed layer, glass fiber fireprotection layer and the fire-resistant sheath of nanoscale halogen-free anti-flaming polyolefin successively, make the insulation property of cable better, fire resistance is strong, structure is simple, reasonable in design.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment
