Abstract
The utility model discloses a heat-resistant flame-retardant variable frequency cable. A plurality of insulated cores are stranded to form a cable core. A filling layer is arranged in a gap of the cable core. Each insulated core consists of a conductor, a low smoke zero halogen glass fiber band and an insulating layer from inside to outside. Copper wires are woven outside each insulated core to form a first shielding layer. The insulating layers are made of flame-retardant silicon rubber insulating materials. The low smoke zero halogen glass fiber band, an inner jacket, a total shielding layer, a belting layer, a jacket reinforcing layer and an outer protection layer are coated outside the cable core and the filling layer sequentially. The product of the utility model integrates various performances of good flexibility, high temperature resistance, moisture resistance, ozone aging resistance, ageing resistance, high flame retardance, corrosion resistance and the like into one body and can be widely used in places with requirements on both higher temperature of the working environment and flame retardance and frequent movement of the cable.

The frequency-changing cable of Xiao Shouing has common frequency-changing cable, fire-retardant frequency-changing cable, high temperature resistant frequency-changing cable, humidity frequency-changing cable, anticorrosion frequency-changing cable etc. in the market, the main performance of these frequency-changing cables is single, can not be adapted to require the occasion of multinomial security performance.Development along with society, performance requirement to cable is more and more higher, promptly require a kind of cable to have multiple performance, different occasions also have nothing in common with each other to the requirement of cable simultaneously, the occasion that has just requires cable to have high temperature resistant, humidity, resistance to oxidation, anti-ozone aging, high flame retardant, anticorrosion, softness etc., and the cable that has single security performance thus on the market can not guarantee safe operation.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of possess high temperature resistant, humidity, resistance to oxidation, anti-ozone aging, high flame retardant, the heat-resisting flame-retardant frequency-changing cable of softness and Corrosion Protection preferably.
The utility model technical solution problem adopts following technical scheme:
The heat-resisting flame-retardant frequency-changing cable, the edge cores that thoroughly do away with are twisted into cable core more, be provided with packed layer in the cable core gap, described insulated wire cores from-inner-to-outer is made of conductor, low smoke and zero halogen glass fibre belt and insulating barrier, outside each insulated wire cores, weave copper wire first screen then, described insulating barrier adopts the flame-proof silicon rubber insulating material to make, and is coated with low smoke and zero halogen glass fibre belt, inner sheath, total screen, belting layer, sheath reinforced layer and outer jacket outside described cable core and packed layer successively.
Described outer jacket is made by the flame-proof silicon rubber sheath material.
Described first screen and total screen are the copper wire woven shield.
Described packed layer is the glass fibre gasket for packing.
Described belting layer is to be coated on the outer low smoke and zero halogen glass fibre belt of total screen.
Described restrictive coating reinforced layer is the weaving fiberglass yarn.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Conductor adopts the copper core compacted stranded conductor of the 2nd class, can prevent the corrosion of moisture content and other harmful substance; Insulating material adopts the import flame-proof silicon rubber to make, and this material not only has good resistance to elevated temperatures, high flame resistance and softness, and maximum operating temperature reaches 200 ℃, and maximum operating temperature reaches 350 ℃ during short circuit; The sheath reinforced layer adopts weaving fiberglass yarn, the stretching resistance effect that has improved cable; Outer jacket adopts import flame-proof silicon rubber sheath material, and this material has good flame retardant property, resistance to low temperature, and Corrosion Protection can lay under-80 ℃ of ambient temperatures, the operation of working under-80 ℃～200 ℃ environment.The utility model product has high flame retardant, high temperature resistant, humidity, advantage such as softness and Corrosion Protection preferably, can be widely used in high temperature resistant, humidity and frequent place of moving.In a word, this utility model product is a kind of new product that performances such as fire-retardant, high temperature resistant, humidity, softness and anticorrosion are integrated in one, and vast market prospect is arranged.
