Description
Technical field
The utility model is related to electrical control cable field more particularly to a kind of low-smoke non-halogen flame-retardant explosion-proof type electric meters
Cable.
Background technology
At present in daily life, it using cable as the supply of electric power of instrument and the carrier of signal transmission, has applied
Among all trades and professions, and in special industry, working environment is possible to that the special circumstances such as explosion can occur, and cable is above-mentioned
It can be preserved in environment and rely on the explosion-proof of itself entirely.And current anti-explosion cable can mix halogen material during fabrication, lead
It sends a telegraph cable and generates larger flue dust in burning, and the intensity of cable is insufficient, it is bad in the protecting effect protected to cable core,
And the heat insulation of thermal insulation layer is insufficient, is easy to cause cable core heat damage.Therefore, solve anti-explosion cable there are high cigarette situation and
The problem of intensity deficiency is just particularly important.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of low-smoke non-halogen flame-retardant explosion-proof type electric meter electricity
Cable is made restrictive coating by low smoke and zero halogen material, and is protected to cable conductor by anti-explosion blocking layer and thermal insulation layer, solution
Anti-explosion cable of having determined has that high cigarette situation and intensity are insufficient.
The utility model provides a kind of low-smoke non-halogen flame-retardant explosion-proof type electric meter cable, including cable core and package cable core
Inner insulating layer is enclosed with flame-retardant layer outside the inner insulating layer, is enclosed with armor outside the flame-retardant layer, outside the armor
Portion is enclosed with restrictive coating, and the restrictive coating is made of low smoke and zero halogen material, and anti-explosion blocking layer, institute are enclosed with outside the restrictive coating
It states and is enclosed with thermal insulation layer outside anti-explosion blocking layer, shielded layer is enclosed with outside the thermal insulation layer, is enclosed with outside the shielded layer
Oversheath.
Further improvement lies in that：Reinforcing rib is installed in the anti-explosion blocking layer, the reinforcing rib is evenly distributed on explosion-proof resistance
In interlayer.
Further improvement lies in that：It is provided with cooling tube in the thermal insulation layer, coolant liquid is perfused in the cooling tube.
Further improvement lies in that：It is interspersed with stainless steel wire in the flame-retardant layer, flame retardant effect is increased by stainless steel wire.
The beneficial effects of the utility model：Be made restrictive coating by low smoke and zero halogen material, and by anti-explosion blocking layer and
Thermal insulation layer protects cable conductor, improves the intensity of cable, and increases the protective capability of cable by reinforcing rib, passes through
Cooling tube promotes the heat insulation of thermal insulation layer, extends the service life of cable, and increases the safety of cable core.
