Description
Technical field
The utility model is related to electric wire fields, and in particular to a kind of ceramic polyolefin fire resistant flame retardant cable.
Background technology
Currently, common fire-resisting cable is overlapped wrapped phlogopite fire resistant belt or synthetic mica fire resistant belt outside using conductor, then squeeze
Make the structure of insulation.Slow due to being overlapped wrapped fire resistant belt speed of production, efficiency is low, increases manufacturing cost.Therefore fire resisting is improved
The production efficiency of cable causes concern.
Utility model content
The purpose of this utility model is to provide one kind having good fire resisting, high temperature resistant, fire-retardant, environmentally friendly and superior mechanical
The ceramic polyolefin fire resistant flame retardant cable of barrier propterty ensures that cable can circuit be just within the regular hour when fire occurs
Often operation, and non smoke and poison gas release, the safe escape of support personnel and being smoothed out for fire-fighting.
The utility model solves the technical solution that above-mentioned technical problem is taken：
A kind of ceramic polyolefin fire resistant flame retardant cable, the cable include flame retardant sheath layer, oxygen barrier successively from outside to inside
Layer, fire-resistant wrapping tape and cable core；The cable core is twisted by several insulated single wires, and the gap filling between insulated single wire has resistance
Filler is fired, the insulated single wire is disposed with insulating layer, flame retardant coating and conductor from outside to inside；The flame retardant coating is by ceramics
Change polyolefin to extrude.
The conductor uses copper wire.
The insulating layer uses polyvinyl chloride or crosslinked polyethylene.
The fire-resistant wrapping tape, which is that the overlapping of high fire-retardance glass tape is wrapped, to be formed.
The oxygen barrier layer is the oxygen barrier filler material of halogen-free and low-smoke flame-retardant polyolefin.
The flame retardant sheath layer is the thermoplastic halogen-free and low-smoke flame-retardant polyolefin material extruded outside oxygen barrier layer.
The beneficial effects of the utility model are embodied in：
Existing fire-resisting cable is wrapped phlogopite fire resistant belt or synthetic mica fire resistant belt to be overlapped outside conductor, then extrude absolutely
Edge material, the utility model is related to fire resistant flame retardant cable the resistance to of cable is improved by the adjustment and application to the construction of cable
Fiery performance and production efficiency.Flame retardant coating in the utility model is extruded using ceramic polyolefin, meets igneous porcelain, not only resistance to
Fiery function admirable, and production efficiency is high.Flame retardant coating, fire-resistant wrapping tape form ceramic material when cable encounters fire, at porcelain,
Fire resisting truly is can reach, oxygen barrier layer, fire retardant jacket decomposite hydrate when cable encounters fire, prevent fire
Flame is spread, and plays flame retardant effect, ensure cable when fire occurs can within the regular hour circuit normal operation.This practicality is new
Raw material employed in type are smokeless, Halogen, non-toxic material, and not will produce smog in high temperature or flame and have
Poisonous gas belongs to environment-friendly type fire resistant flame retardant cable.
Further, oxygen barrier layer uses the oxygen barrier filler material of LSOH anti-flaming in the utility model, and oxygen index (OI) is high, meets fire and decomposes
Go out to prevent the moisture of propagation of flame, there is good flame retardant effect.
