Abstract
The utility model discloses a bury special power cable of protection against rodents ant urban area, including leading body and neutral conductor the equal cladding in the outside of leading body and neutral conductor have the polyurethane insulating layer, be central symmetry with three leading body and place, be provided with neutral conductor between per two adjacent leading bodies, strand three leading bodies and three neutral conductor into the cable core, crowded package has the synthetic polyethylene inner sheath of packing protection against rodents ant outside the cable core, wrap two-layer protection against magnetism stainless steel around the band outside protection against rodents ant synthetic polyethylene inner sheath, wrap the band outward at protection against magnetism stainless steel and have the covering that blocks water around the band, have protection against rodents ant synthetic polyethylene oversheath around the band outside crowded package that blocks water. The utility model discloses have the function that prevents that the mouse from nibbling and stinging and white ant destroy, have simultaneously and prevent that moisture from soaking the inside and lead to the ageing phenomenon of insulating water tree of cable, avoided the emergence of accidents such as cable puncture, short circuit, conflagration, guaranteed the safe operation and the design life of cable.
Description
Technical Field
The utility model relates to the technical field of cables, especially, relate to a city buries special power cable of protection against rodents ant for to the power supply control system in the higher place of electrical safety in city underground direct-burried cable or the cable pit.
Background
In the cables which are used in the underground city or in the cable trench in China at present, a lot of running faults are caused by the damage of rats and ants, hidden dangers are brought to power utilization safety, and the special power cables for underground rat and ant prevention are researched and developed in a targeted mode according to the information condition fed back by a user as a professional manufacturer of electric wires and cables, so that the fault rate of the cables in normal running is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a city buries special power cable of protection against rodents ant in order to remedy prior art's defect.
The utility model discloses a realize through following technical scheme:
the utility model provides a bury special power cable of protection against rodents ant in city, including leading body and neutral conductor the outside of leading body and neutral conductor all in proper order the cladding have polyurethane insulating layer and glass fiber protection against rodents layer, be central symmetry with three leading body and place, be provided with neutral conductor between per two adjacent leading bodies, bind three leading bodies and three neutral conductor and strand into the cable core, the crowded package has the synthetic polyethylene inner sheath of packing protection against rodents ant outside the cable core, wrap two-layer antimagnetic stainless steel around the band outside the synthetic polyethylene inner sheath of protection against rodents ant, it has the covering of package that blocks water around the band outside the package that blocks water, it has the synthetic polyethylene oversheath of protection against rodents ant to extrude the package outside the package around the band.
The main conductor and the neutral conductor are both made of soft thin oxygen-free copper wires.
The water-blocking wrapping layer is longitudinally wrapped by the semi-conductive water-blocking tape, layers are wrapped by the semi-conductive water-blocking tape, and gaps among the stranded wires are filled with a water-blocking yarn pressing structure.
The glass fiber rat-proof layer adopts a glass fiber belt internally provided with microencapsulated pungent taste components.
The utility model has the advantages that: the utility model discloses have the function that prevents that the mouse from nibbling and stinging and white ant destroy, have simultaneously and prevent that moisture from soaking the inside and lead to the ageing phenomenon of insulating water tree of cable, avoided the emergence of accidents such as cable puncture, short circuit, conflagration, guaranteed the safe operation and the design life of cable.
