Abstract
The utility model discloses a three-phase five-wire cable which is convenient to install. The three-phase five-wire cable includes a center core wire, four side core wires, insulating layers and a sheath. The side core wires are uniformly distributed around the center core wire. The insulating layers are arranged between the wires. The side core wires, the center core wire and the insulating layers are all coated in the sheath. The three-phase five-wire cable has a simple structure and is easy to manufacture. Only with the arrangement of one cable, a neutral line and a ground lead are connected and are separate. Therefore, security is increased, system operation is stable, cost is reduced, and it is convenient to install.
Description
Technical field
The utility model relates to a kind of cable of Three-phase five-wire electric power system, relates in particular to a kind of Three-phase five-wire cable of being convenient to install.
Background technology
In the prior art, power circuit often adopts three-phase four wire system, and a quad lays, and the neutral line is also made ground wire and used, and system is unstable, operate dangerously, for assurance safety, now uses the Three-phase five-wire system instead.But do not have five-core cable in the existing Three-phase five-wire system, common way is that one is four-core with two cable layings, and one is single core, and single core is made earth connection and used.Owing to lay twice, increase cost, and construction inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of Three-phase five-wire cable of being convenient to install with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises middle heart yearn, limit heart yearn, insulating barrier and sheath, described middle heart yearn is one, described limit heart yearn is four, described limit heart yearn is uniformly distributed in around the described middle heart yearn, etween the lines is provided with described insulating barrier, and described limit heart yearn, described middle heart yearn and described insulating barrier all are coated in the described sheath.
Particularly, the cross section of described middle heart yearn is circular, and the cross-sectional area of four described limit heart yearns equates.
The utility model only needs a laying installation to get final product success, because the neutral line separates with ground wire, system's operation is more stable.
The beneficial effects of the utility model are:
The utility model is simple in structure, and is easy to manufacture, only need establish a cable, namely connects the neutral line and earth connection, and therefore two lines separately, increased safety, system run all right, and reduced cost, the convenient installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: heart yearn, 2-sheath, 3-insulating barrier, 4-limit heart yearn among the 1-.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings: the utility model comprises middle heart yearn 1, limit heart yearn 4, insulating barrier 3 and sheath 2, middle heart yearn 1 is one, limit heart yearn 4 is four, limit heart yearn 4 is uniformly distributed in around the middle heart yearn 1, etween the lines is provided with insulating barrier 3, and limit heart yearn 4, middle heart yearn 1 and insulating barrier 3 all are coated in the sheath 2.The cross section of middle heart yearn 1 is circular, and the cross-sectional area of four limit heart yearns 4 equates.
The utility model only needs a laying installation to get final product success, because the neutral line separates with ground wire, system's operation is more stable.Therefore, increased safety, system run all right, and simple in structure, easy to manufacture, reduced cost, the convenient installation.
Claims (2)
