Abstract
The utility model discloses a flame-retardant ethylene propylene rubber insulating power cable, comprising a core and a core belting layer. The core comprises cable conductors and ethylene propylene rubber insulating layers, wherein the cable conductors are wrapped by the ethylene propylene rubber insulating layers. The core belting layer comprises a first flame-retardant belting layer, a shielding layer, a second flame-retardant belting layer and a cable flame-retardant over sheath from inside to outside. With the adoption of the above technical scheme, the core belting layer comprises the first flame-retardant belting layer, the shielding layer, the second flame-retardant belting layer and the cable flame-retardant over sheath from inside to outside, so that the flame-retardant performance of the cable is enhanced.
Description
Technical field
The utility model relates to a kind of inflaming retarding ethylene propylene rubber insulated power cable.
Background technology
Present domestic midium voltage cable is used the having relatively high expectations of epr cable compound, and is just very important as the selection of the ethylene-propylene rubber of epr cable compound base material.Electrical property, processing characteristics as the ethylene-propylene rubber of base-material need to be got well also will have certain sulfurating strength.At present, the mesolow ethylene propylene rubber insulated cable generally uses, and many standards have the regulation of ethylene propylene rubber insulated cable, but the fire resistance of existing ethylene propylene rubber insulated cable does not reach requirement, and the fire resistance of cable is not strong.
The utility model content
Technical problem to be solved in the utility model provides a kind of inflaming retarding ethylene propylene rubber insulated power cable, and fire resistance is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the inflaming retarding ethylene propylene rubber insulated power cable, comprise core, core belting layer, described core comprises the ethylene propylene rubber insulated layer of cable conductor and this cable conductor of coating, and described core belting layer comprises the first fire-retardant belting layer, screen, the second fire-retardant belting layer, cable-flame retardant oversheath from inside to outside.
As preferably, the described first fire-retardant belting layer, the second fire-retardant belting layer are the low smoke and zero halogen belting layer.
As preferably, described core is many, and the space between the core is filled by the polypropylene flame redardant filler.
The utility model has strengthened the fire resistance of this cable owing to having adopted technique scheme, core belting layer to comprise from inside to outside the first fire-retardant belting layer, screen, the second fire-retardant belting layer.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Figure 1 shows that the utility model inflaming retarding ethylene propylene rubber insulated power cable, comprise core, core belting layer, described core comprises the ethylene propylene rubber insulated layer 2 of cable conductor 1 and this cable conductor 1 of coating, and described core belting layer comprises the first fire-retardant belting layer 4, turnkey copper strip shielding layer the 5, second fire-retardant belting layer 6, PVC cable jacket 7 from inside to outside.Described core is many, and the space between the core is filled by polypropylene flame redardant filler 3.The described first fire-retardant belting layer, the second fire-retardant belting layer are the low smoke and zero halogen belting layer.
Pollution-free when the utility model inflaming retarding ethylene propylene rubber insulated power cable is produced, meet environmental requirement.After adopting cross-linking radiation technique, improve the fire resistance of insulating barrier, can use in fire-retardant occasion of having relatively high expectations, can satisfy better the market demand of following shipbuilding, colliery, ocean engineering and dress cable in stock.Can be used for the mobile occasion of the needs such as modern architecture group, large-scale urban operating mechanism construction, shipbuilding and traffic engineering, the convenient especially mechanized equipment that is used for operation.
