Description

A kind of New Mineral insulation Halogen jacketed cable

Technical field

Power cable field is the utility model is related to, more particularly to a kind of New Mineral insulation Halogen jacketed cable.

Background technology

With the fast development of national economy and the continuous improvement of living standards of the people, society's electricity consumption amount greatly increases, respectively The steep increasing of kind electrical equipment consumption, electrical fire accident also increase severely therewith.According to statistics, fire occurs every year for China ten thousand about more than ten Rise, more than 10 hundred million yuan of direct property loss.Wherein, by electric wire short circuit, excess load, electrical equipment failure etc., electrically reason triggers Fire account for sum 30%, the frequency of electrical fire and caused loss are occupied first of all kinds of fire.In electricity In gas fire, the fire triggered by electric wire accounts for half.Therefore the fire-retardant and fire safety problem people on electric wire Increasingly pay attention to, the fire-retardant and fire protection requirement to electric wire is also higher and higher.

Fireproof cable refers to fire-retardant or fire resistance cable, and the cable with fire protecting performance is main currently on the market It is divided into three classes, one kind is that glass wool cloth band built up mica piece is wrapped in copper wire outer surface as fireprotection layer, the cable fire-proof performance Difference, the fire prevention temperature and fire resistance period of product can not reach the design specification of modern high-rise building, while the glass fiber of outer layer exists Fire protecting performance is poor during high temperature；Another kind is the rigid fireproof cable for using mineral powders as insulating layer, the cable outer layer For copper pipe, rigid fireproof cable is laid with, complex process, production difficulty is big, and production and use cost are higher, and bending property is poor, Install and construct and is relatively difficult；Last one kind is silicon rubber insulated cable, and silicone rubber fireproof temperature is low, thus fire protecting performance compared with Difference, fire, which occurs, can discharge toxic gas, and there is deficiency, it is impossible to meets the needs of industry development.

In conclusion the defects of being directed to the prior art, it is accordingly required in particular to a kind of New Mineral insulation Halogen jacketed cable, with solution Certainly the deficiencies in the prior art.

Utility model content

For the deficiencies in the prior art, use in practice is influenced, the utility model proposes a kind of New Mineral Insulate Halogen jacketed cable, novel in design, improves product insulated wire cores and ensures insulation performance under high temperature and fire condition Validity, improves the security that product uses.

To achieve these goals, the technical solution of the utility model is as follows：

A kind of New Mineral insulation Halogen jacketed cable, including oversheath, copper core conductor, copper core conductor are led to by conductor wire core Cross inorganic insulation layer parcel to be made, the material that inorganic insulation layer uses is filled with for silica between oversheath and copper core conductor Thermal insulation layer, for the material that thermal insulation layer uses for Halogen silicon porcelain cement, the surface of inorganic insulation layer is both provided with high sub- code insurance sheath, high score The material that sub- protective layer uses is the chlorinated rubber containing glass fibre.

The equal arranged tangential of polymer protection layer between the adjacent copper core conductor of the utility model.

Further, the section of the conductor wire core is rounded, and every conductor monofilament of conductor wire core is circular copper wire, circle Copper wire is provided with tin coating for surface.

Further, the thickness of the inorganic insulation layer is 0.5-1mm.

Further, for the material that the oversheath uses for polyvinyl chloride or crosslinked polyethylene, the surface of oversheath is in spiral shell Revolve shape.

Further, the thickness of the polymer protection layer is 3-8mm.

The beneficial effects of the utility model are：The utility model is simple in structure, improve product insulated wire cores in high temperature and Ensureing the validity of insulation performance under fire condition, improve the service life of product, cable is unlikely to deform, preferable pliability, Easy to construct and install, cable safety in utilization is improved, it is novel in design, it is a kind of good innovation scheme.
