Abstract
The utility model discloses a three -core power cable with reserve structure, including cross support frame that can ceramicization material extrusion molding, four regions that the cross support frame is cut apart are equipped with the cross -section respectively and be 14 circular shape silicon rubber carrier layers, wherein all are equipped with electric insulated conductors in the three silicon rubber carrier layer, are equipped with the preformed hole in the another one carrier layer, outside cross support frame and the silicon rubber carrier layer in proper order the cladding have high temperature resistant glass fiber tape to wind covering, low carbon polymer fire resistance and insulation inner liner, high -strength fiber silk weaving layer, polysulfone (PSO) oversheath layer. The utility model discloses structural design is novel, keeps apart each electric insulated conductors through cross -shaped supporting frame and silicon rubber carrier layer, electric phenomena can not appear leaking, when the disconnected core of certain electric insulated conductors appearing, can add the installation of wire interlude according to actual conditions, facilitate the use, reduced the cost that the maintenance was changed.
Description
Technical field:
This utility model relates to power cable, particularly relates to a kind of three core power cables with alternate configuration.
Background technology:
China's economic growth continuously and healthily, the huge market space is provided, the allure that Chinese market is strong so that the world all focuses on Chinese market sight for cable products, in the decades that reform and opening-up is short, the huge production capacity that China's cable manufacturing industry is formed allows the world regard with special esteem.
When three phase supply, the cable on market often occurs in which that an impaired even fracture of conductor runs out of electricity, leaky easily occurs; cable burns the replacing causing needing to carry out whole cable; causing waste, and need to go to buy quite inconvenience, cost increases.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of three core power cables with alternate configuration, and cable is difficult to leaky occur, can intert according to practical situation Extension Wire and install, and convenient use reduces the cost that maintenance is changed.
The technical solution of the utility model is as follows:
Three core power cables with alternate configuration, it is characterized in that: including can the cross bracing frame of ceramic material extrusion moulding, four regions that cross bracing frame is divided into are respectively equipped with the silicone rubber carrier layer that cross section is 1/4 circle, wherein three silicone rubber carrier layer are equipped with electric insulation core, another one carrier layer is provided with preformed hole, outside described cross bracing frame and silicone rubber carrier layer, is coated with high temperature resistance glass fiber band lapping layer, low carbon macromolecule hot-face insulation inner liner, high strength fibre silk braid, polysulfones external sheath layer successively.
Described three core power cables with alternate configuration, it is characterized in that: the aperture of described preformed hole is more than the external diameter of electric insulation core, on the inwall of preformed hole, adhesion has a pull rope arranged along cable axial direction, and pull rope typically uses aramid fiber tow or terylene tow.
The utility model has the advantages that:
This utility model novel in structural design, is isolated each electric insulation core by cross supporting frame and silicone rubber carrier layer, is not had leaky；Occur certain root electric insulation core break core time, can intert according to practical situation Extension Wire and install, convenient use, reduce the cost that maintenance is changed.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
Three core power cables with alternate configuration, including can the cross bracing frame 1 of ceramic material extrusion moulding, four regions that cross bracing frame 1 is divided into are respectively equipped with the silicone rubber carrier layer 2 that cross section is 1/4 circle, wherein three silicone rubber carrier layer 2 are equipped with electric insulation core 3, another one carrier layer is provided with outside preformed hole 4, cross bracing frame 1 and silicone rubber carrier layer 2 and is coated with high temperature resistance glass fiber band lapping layer 5, low carbon macromolecule hot-face insulation inner liner 6, high strength fibre silk braid 7, polysulfones external sheath layer 8 successively.
The aperture of preformed hole 4 is more than the external diameter of electric insulation core 3, and on the inwall of preformed hole 4, adhesion has a pull rope 9 arranged along cable axial direction, and pull rope 9 typically uses aramid fiber tow or terylene tow.
This utility model novel in structural design, is isolated each electric insulation core 3 by cross supporting frame 1 and silicone rubber carrier layer 2, is not had leaky；Occur certain root electric insulation core break core time, can be readily detected by the instrument such as electroprobe, circuit tester is which root goes wrong, and pull rope 9 can be utilized to intert according to practical situation Extension Wire and install, and convenient uses, and reduces the cost that maintenance is changed.
