Embodiment 1
It is the fire-retardant branch cable of a kind of pvc sheath provided in this embodiment with reference to figure 1, in figure, is primarily adapted for use in
Middle-high building, industrial premises, highway, bridge, etc. conveying voltage in 1000V power below and lighting power supply system.Pass through
Site operation labor intensity can be greatly reduced in prefabricated branch, shorten the construction laying time, and power supply and distribution cost is made obviously to drop
It is low.And sealing effect is good, has good flame retardant effect, need not safeguard for a long time, service life is long.
Specifically, the fire-retardant branch cable of the pvc sheath comprising after 10 branch of leader cable 10 and leader cable
First branch cable 11 and the second branch cable 12.The fire-retardant branch cable of pvc sheath further includes pvc sheath 13, polychlorostyrene
Ethylene sheath 13 is tightly connected with leader cable 10, the first branch cable 11 and the second branch cable 12 respectively.I.e. casing insulation is using excellent
It is molded in the pvc material of common cable oversheath, insulation and sealing performance are excellent, specious, and pass through sealing
Setting, ensure that waterproof moisture-proof effect in use.
Further, the fire-retardant branch cable of pvc sheath further includes seal ring set 20, leader cable 10, the first branch cable
11 and second branch cable 12 connect respectively with pvc sheath 13 by seal ring set 20.It is realized more preferably using seal ring set 20
Sealing effect, and connected using prefabricated seal ring set 20, directly make when reducing manufacture pvc sheath 13 and leader cable 10,
The difficulty that first branch cable or the second branch cable 12 are tightly connected.It should be noted that in other specific implementation modes, also
