Description
Technical field
The utility model relates to a kind of power circuit scissors crossing insulating protection stiffener, the insulation when it is applied to medium and high voltage power line road and low pressure or the scissors crossing of light current circuit.
Background technology
At present, power circuit, particularly mesolow circuit scissors crossing safe distance is perplexing power supply enterprise inadequately for a long time, some power circuit adheres to specification when construction, but owing to the variation of circuit running environment or the reasons such as violation intrusion of other line facility, cause line pitch too near, low pressure or other light current circuit, initiation equipment and personal injury are scurried in the high-tension electricity discharge.Electric power enterprise often adopts following several method in order to solve the contradiction of circuit scissors crossing: transform to power circuit or by the infringement circuit (1).This is the scheme of thoroughly dealing with problems, but owing to reasons such as investment are big, power cut construction is difficult, involve many areas, often is difficult to realize; (2) take temporary preventive measure, use some insulating material, as thermoplastic material, mistake tree belt etc. circuit scissors crossing section is carried out the insulating protection reinforcement, can play temporary transient effect, but owing to adopt material mixed and disorderly, lack of standardization, its insulation level is difficult to be guaranteed, and interface does not generally have effective waterproof measure in addition, very easily cause inner lead corroded by rain, dew and corrosion is serious, long-time use meeting will make local cable heating impaired.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of power circuit scissors crossing insulating protection stiffener of special use is provided, make it not only have the good insulation barrier propterty, simultaneously its easy construction, good airproof performance, electric power cable itself is also had protective action preferably.
Power circuit scissors crossing insulating protection stiffener of the present utility model includes the inner insulating layer that coats successively in the electric power cable periphery, shaping packed layer and high-strength insulation overcoat, an insulation full skirt is respectively arranged at the two ends of whole stiffener, described inner insulating layer is an insulating polymeric material, it is close to the electric power cable outer surface, described shaping packed layer is the insulating material with hot melt, it is filled in the inner insulating layer periphery, described high-strength insulation overcoat is the sheet material that a slice is made by the anti-aging material contracting with heat, it is coated on the outermost layer of stiffener, and its two edges that dock mutually connect by the junction button of a strip.There is a slot longitudinally described junction button inboard, and respectively there is the lengthways of rod of a projection at two edges that the high-strength insulation overcoat docks mutually, two ribs all are inserted in the slot of junction button, locking achieves a butt joint, the junction button outside at strip also has a plurality of horizontal notches in the compartment of terrain, to adapt to the diastrophic needs of cable certain limit.Described insulation full skirt is made up of mutual two involutory semi-rings, and its main body is covered by within above-mentioned each layer, and its canopy retaining is at the two ends of whole stiffener, to increase creepage distance.
The utility model is because the multilayer insulation reinforcement material that adopts different performance carries out insulating protection to the electric power cable of scissors crossing section, good insulation preformance not only, and have good waterproof sealing performance and higher outer intensity and ageing resistace, its construction simultaneously is also very convenient.
