Abstract
The utility model discloses a polyvinyl chloride insulating polyvinyl chloride sheath waterproof power cable, and relates to the technical field of cable manufacturing. The polyvinyl chloride insulating polyvinyl chloride sheath waterproof power cable comprises a cable core, wherein the outer side o f the cable core is sequentially provided with a wrapping belt layer, a moisture barrier and a sheath layer; and the cable core comprises five groups of wire cores, each group of the wire cores comprises a plurality of mutually stranded copper conductors, and the outer side of the plurality of mutually stranded copper conductors is wrapped by an insulating layer. According to the utility model, the insulating layer and the sheath layer are additionally provided with the moisture barrier therebetween, thereby being capable of effectively solving a problem that the internal part of cables is easily damped and invaded by water because of cracking of cable plastic and thus affects the conductivity or causes accidents.
Description
Technical field
The utility model relates to cables manufacturing technical field.
Background technology
Traditional polyvinyl chloride-insulated polyvinyl chloride power cable, because pvc material intensity is low, be prone to the phenomenons such as fracture, crack, causes cable inner easily moist, easily water inlet, thus affect electric conductivity, or cause accident.
Utility model content
The utility model object is for above problem, provides a kind of and is not prone to that fracture, intensity are high, the polyvinyl chloride-insulated polyvinyl chloride waterproof power cable of good water-proof effect.
The utility model comprises cable core, in described cable core outside, sets gradually belting layer, moisture-proof layer and restrictive coating; Described cable core comprises five groups of cores, and every group of core comprises respectively some mutual stranded copper conductors, at some mutual stranded copper conductor outside difference wrap insulate layers.
The utility model has added a moisture-proof layer between insulating barrier and sheath, can effectively solve because cable plastics cracking causes cable inner easily moist, and easily water inlet, thus affect electric conductivity, or cause the problem of accident.
Five groups of cores described in the utility model are that one group of cross section is that circular core and four groups of cross sections are that fan-shaped core forms, and described four groups of cross sections are that fan-shaped core be take cross section centered by circular core, are distributed in respectively cross section and are the surrounding of circular core.Make the construction of cable compacter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core, in cable core outside, sets gradually belting layer 1, moisture-proof layer 2 and restrictive coating 3; Cable core comprises five groups of cores 4, five groups of cores 4 are that one group of cross section is that circular core 4-1 and four groups of cross sections are that fan-shaped core 4-2 forms, four groups of cross sections are that fan-shaped core 4-2 be take cross section centered by circular core 4-1, are distributed in respectively cross section and are the surrounding of circular core 4-1; Every group of core 4 comprises respectively some mutual stranded copper conductors 5, at some mutual stranded copper conductor 5 outsides difference wrap insulate layers 6.
