Description

Cable for entering house

Technical Field

The utility model belongs to the technical field of the cable technique of registering one's residence and specifically relates to a cable registers one's residence.

Background

At present, the home cable generally adopts a YJV structure, and the cable has two defects, namely, the cable cannot prevent a user from stealing electricity and cannot monitor electricity consumption data in real time. And the cable core adopts the transposition structure, and the cable external diameter is big, leads to construction cost to increase.

SUMMERY OF THE UTILITY MODEL

The applicant aims at the defects in the prior art and provides a house-entry cable with a reasonable structure, a concentric conductor structure is adopted, the outer diameter of the cable is small, a communication wire core is added, electricity stealing can be prevented, and the electricity utilization condition can be monitored in real time.

The utility model discloses the technical scheme who adopts as follows:

the service cable comprises a solid conductor and a conductor insulating layer extruded on the solid conductor, wherein the solid conductor and the conductor insulating layer form an insulating wire core; a plurality of concentric conductors and at least four communication wire cores are sparsely wound outside the insulation wire core, and the sum of the sectional areas of the plurality of concentric conductors is equal to the sectional area of the solid conductor; the communication wire core comprises a copper conductor and a communication insulating layer extruded outside the copper conductor; a layer of wrapping tape is simultaneously wrapped outside the concentric conductor and the at least four communication wire cores; a tearing rope is directly dragged in the wrapping band, and an outer sheath is extruded outside the wrapping band.

As a further improvement of the above technical solution:

the solid conductor is made of copper, aluminum or aluminum alloy, and the sectional area of the solid conductor is 10mm 2-25 mm 2.

The concentric conductor is made of copper, aluminum or aluminum alloy, and the diameter of the monofilament is 0.5 mm-1.0 mm.

The tearing rope is made of a nylon rope.

The conductor insulating layer and the communication insulating layer are both insulated by adopting a cross-linked polyethylene insulating material or linear low-density polyethylene.

The outer sheath is made of ultraviolet-resistant polyethylene sheath material.

The utility model has the advantages as follows:

the utility model discloses compact structure, reasonable, solid conductor adopts solid construction, low in production cost, and same cross-section can improve 5% than stranded conductor electric conductive property.

The cable has increased four communication sinle silks, and two of them are used for the control, and two are used for the transmission data. Compared with the traditional house-entering cable, the cable is safer and more convenient to use.

The cable sheath is internally provided with a tearing rope, so that the sheath can be torn by bare hands, and the cable sheath is convenient to install.

The insulating sheath is made of environment-friendly materials, and does not harm the environment and human beings.

The sheath material adopts uvioresistant polyethylene, and the service life of the cable can be prolonged by more than 5 years.
