Description

Novel ceramic silicon rubber mineral insulation copper sleeve fireproof cable

Technical Field

The utility model particularly relates to a novel pottery silicon rubber mineral insulation copper sheathing fireproof cable.

Background

The cable is a general term for optical cables, electric cables and the like. The cable is widely applied to power transmission in life, is mainly used for controlling multiple functions of installation, equipment connection, power transmission and the like, plays an extremely important role in various industries, and is a common and indispensable object in daily life.

If the cable is short-circuited or broken in the using process, the risk of fire is very likely to occur, and the cable is also likely to be invaded by an external fire source so as to cause a more serious fire; the existing flame-retardant fireproof cable is generally a fireproof protective layer prepared by singly mixing a flame retardant and a cable insulating material, and the cable has poor fireproof and flame-retardant effects; therefore, the cable with better flame-retardant and fireproof effects is very necessary for life of people.

In foretell a novel pottery silicon rubber mineral insulation copper sheathing fireproof cable, be provided with between a plurality of internal insulation parcel portions of pottery silicon rubber insulating layer and keep apart the chamber, keep apart each side of chamber and packing chamber two and correspond the center around to the conductor formation respectively, keep apart the intracavity and be provided with the mineral substance filling layer equally.

In the novel ceramic silicon rubber mineral insulation copper sleeve fireproof cable, the side surfaces of the filling cavity and the isolation cavity corresponding to the conductors are concave inwards, and the isolation end parts corresponding to each other are formed.

Adopt above technical scheme, the utility model discloses following beneficial effect has:

the conductor in the utility model is wrapped in the ceramic silicon rubber insulating layer, the ceramic silicon rubber insulating layer comprises an inner insulating wrapping part and an outer insulating wrapping part which is integrated with the inner insulating wrapping part, and the ceramic silicon rubber insulating layer forms fireproof isolation among the conductors; simultaneously again be equipped with the packing chamber between two adjacent internal insulation parcel portions and be equipped with the mineral substance filling layer in it, the cooperation between mineral substance filling layer and the internal insulation parcel portion further forms the effect of keeping apart the fire prevention between each conductor, has between each conductor when taking place to catch fire, the effect of keeping apart fire prevention, preventing scurrying the fire between each conductor, effectively avoids taking place more serious conflagration condition.

The utility model discloses the pottery is further equipped with between a plurality of internal insulation parcel portions and keeps apart the chamber and be equipped with the mineral substance filling layer in it equally to keep apart the chamber and fill the mineral substance filling layer in the chamber both and keep apart around to forming between each conductor during, further improve the holistic isolation fire prevention effect of cable, improve the security of using.
