Abstract
The utility model discloses a stable and safe electric cable. The stable and safe electric cable comprises insulated conductors, and a foaming polyethylene insulating layer, a rubber metal composite layer and a metal fibre sheath layer are successively disposed outside the insulated conductors. The rubber metal composite layer comprises a rubber compound layer and an electroplating tin powder layer, and the electroplating tin powder layer is disposed between the rubber compound layer and the foaming polyethylene insulating layer. By disposing the rubber compound layer and the electroplating tin powder layer, performance of shielding an electric field is improved; the electroplating tin powder layer and the foaming polyethylene insulating layer are contacted tightly to prevent partial discharge; and due to the metal fibre sheath layer and the rubber compound layer, the inside of the cable can be effectively ensured to be prevented from being attacked by moisture, combination performance of the whole structure of the electric cable is good, good plastic deformation can be generated when the electric cable is bended, the electric cable is not susceptible to mechanical damage of external force, and long-term, stable and safe power transmission demands of the electric cable can be satisfied.
Description
Technical field
The utility model belongs to cables manufacturing technical field, is specifically related to a kind of electric wire of stability and safety.
Background technology
Electric power system is that electrical insulation capability is good with electric wire to the general requirement of its insulating barrier, but for high voltage power cable, must emphasize that material can bear very high electric field strength and have high insulation resistance, and requiring does not almost have impurity or air gap in material, using in different occasions for cable normal transmission electric energy to be extremely important with correct signal transmission, existing insulated cable stability and poor stability, shield effectiveness is bad, and useful life is short.
Application number is the patent " polyvinyl chloride cable " of 201120326006.X, comprises three strand insulation conductors, sets gradually Transposed wind layer, tincopper fuse wire braided armor and pvc sheath layer outward at insulated electric conductor; This patent adopts tincopper fuse wire braided armor in actual production, slower in preparation process, affects range of application, and pvc sheath layer is subject to external force damage effect useful life.
Utility model content
The utility model is in order to make up the deficiencies in the prior art, and the electric wire of a kind of stability and safety, long service life, advantages of good shielding performance is provided.
An electric wire for stability and safety, comprises insulated electric conductor, and insulated electric conductor sets gradually polyethylene foamed insulating barrier, rubber-metal composite bed, metallic fiber sheath outward.
Described rubber-metal composite bed comprises rubber composite layer and electrotinning bisque, and described electrotinning bisque is between rubber composite layer and polyethylene foamed insulating barrier.
The utility model, by rubber composite layer and electrotinning bisque are set, increases conductance, as the path of short circuit current, improves the performance of electric field shielding; Due to electrotinning bisque smooth surface, be difficult for electric field, can and polyethylene foamed insulating barrier between contact closely, can not produce partial discharge; Metallic fiber sheath and rubber composite layer can effectively ensure that the cable inside gas cut that do not make moist attacks, electric wire overall structure excellent bonding performance, when bending, can produce good moulding deformation, not be subject to the mechanical damage of external force, can occasionally meet electric wire for a long time, the transmission of electricity demand of safety and stability.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is a kind of structural representation of the present utility model.
Specific embodiment
