Abstract
The utility model discloses a silicon rubber insulation sheath power cable and relates to a silicon rubber insulation sheath power cable. The silicon rubber insulation sheath power cable comprises a cable conductive core (1) and an insulation sheath which is sheathed outside the cable conductive core (1). The insulation sheath is composed of a silicon rubber insulation layer (2) and a polyvinyl chloride surface layer (3). The silicon rubber insulation layer (2) is arranged at the inner layer, and the polyvinyl chloride surface layer (3) is located outside the silicon rubber insulation layer (2). The thickness of the silicon rubber insulation layer (2) is 0.6 mm to 0.7 mm. The thickness of the polyvinyl chloride surface layer (3) is 0.4 mm to 0.5 mm. The silicon rubber insulation sheath power cable provided by the utility model solves the problems that the surface of the existing silicon rubber cable is easily cracked when used for a period of time in the environment of high temperature, thus the insulation performance of the cable is poor and the service life is short.
Description
Technical field
The utility model relates to the silicon rubber insulation sheath power cable.
Background technology
Silicon rubber power cable is applicable to ac rated voltage 0.6/1KV and following fixedly laying with power transmission line or movable electrical appliances stube cable, product has the characteristics such as heat-resisting radiation, cold-resistant, acid and alkali-resistance and corrosive gas, waterproof, cable electric property under high temperature (high and cold) environment is stable, ageing resistace is outstanding, long service life, be widely used in the industries such as metallurgy, electric power, petrochemical industry, electronics, automobile making.
Silicone rubber for cable has thermal stability preferably, can in high temperature, low temperature, corrosivity, keep good electrical property and flexibility, is applicable to the industries such as metallurgy, electric power, petrochemical industry and has the specific (special) requirements occasion uses such as mobile heatproof.
But existing silicone rubber for cable is used a period of time rear surface easily to chap under hot environment, causes insulating performance of cable poor, useful life is short.
Summary of the invention
The utility model provides the silicon rubber insulation sheath power cable, and the utility model has solved existing silicone rubber for cable and under hot environment, used a period of time rear surface easily to chap, and causes insulating performance of cable poor, the problem that useful life is short.
For addressing the above problem, the utility model adopts following technical scheme: the silicon rubber insulation sheath power cable comprises cable conduction core 1 and the insulating sleeve that is set in cable conduction core 1 outside; Insulating sleeve consists of silicone rubber insulation layer 2 and polyvinyl chloride top layer 3; Silicone rubber insulation layer 2 is positioned at internal layer, and polyvinyl chloride top layer 3 is positioned at silicone rubber insulation layer 2 outsides.
The thickness of described silicone rubber insulation layer 2 is the 0.6-0.7 millimeter, and the thickness on described polyvinyl chloride top layer 3 is the 0.4-0.5 millimeter.
The skin of the utility model insulating sleeve is the polyvinyl chloride top layer, has softness, arbitrarily thin, the cable surface of bending fold, relative thickness is not easy be full of cracks, and insulating performance of cable is good, the advantages such as long service life.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Symbol description in figure: cable conduction core 1, silicone rubber insulation layer 2, polyvinyl chloride top layer 3.
Embodiment
below with best embodiment, the utility model is described in detail
.
As shown in Figure 1, the silicon rubber insulation sheath power cable, comprise cable conduction core 1 and the insulating sleeve that is set in cable conduction core 1 outside; Insulating sleeve consists of silicone rubber insulation layer 2 and polyvinyl chloride top layer 3; Silicone rubber insulation layer 2 is positioned at internal layer, and polyvinyl chloride top layer 3 is positioned at silicone rubber insulation layer 2 outsides.
The thickness of described silicone rubber insulation layer 2 is 0.64 millimeter, and the thickness on described polyvinyl chloride top layer 3 is 0.46 millimeter.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection range of the present utility model.
