Abstract
The invention discloses a three-phase five-wire cable convenient to install. The three-phase five-wire cable comprises a middle core wire, edge core wires, an insulating layer and a protective cover, wherein the number of the middle core wire is one, the number of the edge core wires is four, the four edge core wires are evenly distributed around the middle core wire, the insulating layer is arranged between the middle core wire and the edge wires, and the edge core wires, the middle core wire and the insulating layer are all wrapped by the protective sleeve. The three-phase five-wire cable is simple in structure and easy to manufacture, a neutral wire and a grounding wire can be connected only through the cable and are separated, and therefore, safety is increased, the system is stable in operation, cost is reduced, and the three-phase five-wire cable is convenient to install.
Description
Technical field
The present invention relates to a kind of cable of Three-phase five-wire electric power system, relate in particular to a kind of Three-phase five-wire cable of being convenient to installation.
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., system is unstable, operates dangerously, for guaranteeing safety, now uses Three-phase five-wire system instead.But there is no five-core cable in existing Three-phase five-wire system, common way is that one is four-core with two very cable layings, and one is single core, single core is made earth connection and is used.By dry, lay twice, increase cost, and construction inconvenience.
Summary of the invention
Object of the present invention provides a kind of Three-phase five-wire cable of being convenient to installation with regard to being in order to address the above problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes 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 described middle heart yearn surrounding, etween the lines is provided with described insulating barrier, and described limit heart yearn, described middle heart yearn and described insulating barrier are all coated in 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 present invention only needs a laying installation to get final product success, and because the neutral line and ground wire separate, system operation is more stable.
Beneficial effect of the present invention is:
The present invention is simple in structure, easy to manufacture, only need establish a cable, connects the neutral line and earth connection, and two lines are separately, therefore, increased safety, system run all right, and reduced cost, convenient installation.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
In figure: heart yearn, 2-sheath, 3-insulating barrier, 4-limit heart yearn in 1-.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in drawings: the present invention includes middle heart yearn 1, limit heart yearn 4, insulating barrier 3 and sheath 2, middle heart yearn 1 is one, and limit heart yearn 4 is four, and limit heart yearn 4 is uniformly distributed in middle heart yearn 1 surrounding, etween the lines is provided with insulating barrier 3, and limit heart yearn 4, middle heart yearn 1 and insulating barrier 3 are all coated in 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 present invention only needs a laying installation to get final product success, and because the neutral line and ground wire separate, system operation is more stable.Therefore, increased safety, system run all right, and simple in structure, easy to manufacture, reduced cost, convenient installation.
Claims (2)
1. be convenient to the Three-phase five-wire cable of installing for one kind, it is characterized in that: comprise 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 described middle heart yearn surrounding, etween the lines is provided with described insulating barrier, and described limit heart yearn, described middle heart yearn and described insulating barrier are all coated in described sheath.
2. the Three-phase five-wire cable of being convenient to installation according to claim 1, is characterized in that: the cross section of described middle heart yearn is for circular, and the cross-sectional area of four described limit heart yearns equates.
