Abstract
A high voltage resistance guide measurement and control cable is disclosed. The utility model relates to the cable technical field, and particularly relates to the high voltage resistance guide measurement and control cable. The high voltage resistance guide measurement and control cable comprises seven strands of cable cores whose outer side is orderly provided with a second wrapping layer, an aluminum foil shielding layer, an inner sheath layer, an aluminum wire armored layer and an outer sheath layer. A water-resistant ointment filling layer is arranged between the seven strands of the cable cores and the second wrapping layer. Each strand of the cable cores comprises two intertwined insulating conductors whose outer side is provided with a first wrapping layer. Each insulating conductor comprises a solid conductor which is wrapped by an insulating layer outside. The high voltage resistance guide measurement and control cable has the advantages of novel structure, reasonable material collocation, excellent high voltage resistance performance, excellent shielding performance, strong anti-interference ability and high security, and failure phenomena such as misoperation, failed operation and high voltage breakdown can be completely avoided.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to a kind of high pressure resistant guiding measurement and control cable.
Background technology
Along with development of Chinese economy; The urban-rural integration process also obtains develop rapidly; The urban power consumption is striven greatly, and the resident is stable to electricity consumption, safety also proposes new requirement, and State Grid Corporation of China also making great efforts to make always have informationization, the strong intelligent grid of the unification of automation, interactive characteristic; Use the general control cable to carry out the longitudinal difference protection of high voltage power transmission cable in the past; Faults such as misoperation, tripping work, control cable high-voltage breakdown often take place, can not meet the demands, high pressure resistant guiding measurement and control cable is mainly used in the longitudinal difference protection of big capacity, short distance, anti-interference transmission line cable in the urban power network.
Summary of the invention
The utility model is in order to overcome the deficiency of general control cable; Provide a kind of and have that proof voltage height, capacity of short circuit are big, advantages of good shielding performance, anti-induced voltage; And radiation such as externally do not generate electromagnetic waves prevents the high pressure resistant guiding measurement and control cable of characteristics such as relay misoperation work.
The utility model comprises seven strands of cable cores, outside said seven strands of cable cores, sets gradually second lapping layer, foil shielding layer, inner restrictive coating, aluminium wire armour and external sheath layer; Between the said seven strands of cable cores and second lapping layer, the greasy for preventing water packed layer is set; Said per share cable core includes the insulated electric conductor of two pair twists, and first lapping layer is set outside the insulated electric conductor of said two pair twists, and said every insulated conductor includes solid conductor, the wrap insulate layer in the said solid conductor outside.
The utility model adopts solid conductor, extrudes the PE insulation at conductive surface, and it is right to twist into different pitches, isolates and the capacity unmbalance performance to improve cross-talk.The utility model adopts greasy for preventing water to fill, and gets into cable core to stop moisture content.The utility model adopts aluminum foil shielded, has excellent Electro Magnetic Compatibility, and wrapped nonwoven fabrics protection extrudes the low density linear polyethylene inner sheath, to stop any moisture the cable heart is permeated.The utility model adopts many hard circle aluminium wires to be wrapped on the inner sheath, constitutes the cable shield armour, extrudes one deck insulation level external sheath layer at last.
The utility model novel structure, material collocation rationally adopt the multilayer screen technology; Make cable not only conductor have excellent high voltage withstanding performance; Shielding properties is excellent, and antijamming capability is strong, and cable can bear 15kV voltage; Fail safe is high, can avoid phenomena of the failure such as misoperation, tripping work and high-voltage breakdown fully.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is provided with seven strands of cable cores 1, outside seven strands of cable cores 1, sets gradually second lapping layer 2, foil shielding layer 3, inner restrictive coating 4, aluminium wire armour 5 and external sheath layer 6; Between the seven strands of cable cores 1 and second lapping layer 2, greasy for preventing water packed layer 7 is set; Per share cable core 1 includes the insulated electric conductor 8 of two pair twists, and first lapping layer 9 is set outside the insulated electric conductor 8 of two pair twists, and every insulated conductor 8 includes solid conductor 10, at solid conductor 10 outside wrap insulate layers 11.
