Abstract
The invention discloses an insulating variable frequency cable with a crosslinked polyethylene jacket. The insulating variable frequency cable with the crosslinked polyethylene jacket comprises main core conductors, main core insulating layers, monitoring core conductors, monitoring core insulating layers and the crosslinked polyethylene jacket; a main core conductor shielding layer, the main core insulating layer and an insulating nonmetallic shielding layer coat the main core conductor in sequence to form a power core; the monitoring core insulating layer wraps the monitoring core conductor in an extrusion mode to form a monitoring core; three power cores are extruded tangentially, the contact parts of the three power cores are extruded with three monitoring cores in sequence, an anti-static wrapping tape firmly wraps the three power cores and three monitoring cores to form a cable core, a fire-resistant mica tape filling layer is arranged outside the cable core, and a jacket fiber reinforcing layer coats the fire-resistant mica tape filling layer; the crosslinked polyethylene jacket is arranged outside the jacket fiber reinforcing layer. The voltage of the variable frequency cable arrives at 8.7/10 kV; the insulating variable frequency cable with the crosslinked polyethylene jacket has good aging resistance, high temperature and low temperature resistance, static resistance and shielding performance and can be used as a mobile equipment power supply under complex conditions, such as coal mine.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of crosslinked polyethylene jacket insulation frequency-changing cable that applies to open coal mine stope mobile power supply equipment.
Background technology
As everyone knows, China is the big country of a rich coal resources, coal is one of important energy of China, along with the continuous demand of expanding economy to electric power, drive the high speed development of coal industry, also driven the cable development of using for coal mining, along with scientific and technological development, for the more and more high-powers that trend towards of equipment of the resource that cuts coal, the electric wire that has therefore driven equipment connection to use trends towards high electric pressure development.The drag cable that the mobile power supply equipment of the electric pressure 8.7/10kV rank of using for outdoor mining industry is in the market used mainly depends on import, and for a little less than the general cable of the industry especially frequency-changing cable ageing resistance, resistant of high or low temperature, resistance to wear, the characteristic such as tear-proof is poor, and antistatic performance is bad, shield effectiveness is not good, causes electric property bad.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of crosslinked polyethylene jacket insulation frequency-changing cable.
The solution of the present invention is as follows: a kind of crosslinked polyethylene jacket insulation frequency-changing cable, comprises master core conductor, master core insulating barrier, pilot wire core conductor, pilot wire core insulation layer and crosslinked polyethylene oversheath; Described master core conductor is overmolding to power core by master core conductor shield, master core insulating barrier and insulated non-metal screen outward successively; Described pilot wire core conductor is monitored core insulating barrier and extrudes into supervision core; Three tangent extruding of power core, three power core contact site outsides are extruded with successively three and monitor core, three power cores with three monitor cores by antistatic twining package tape tightly wrapped become cable core, described cable core is outside equipped with fire-resistant isinglass belt packed layer, is coated by sheath fabric reinforcement; Described sheath fabric reinforcement is outside equipped with crosslinked polyethylene oversheath.
Between described master core insulating barrier and insulated non-metal screen, be provided with soft copper band.
In described master core insulating barrier, be evenly provided with steel wire.
Described master core conductor is to adopt the zinc-plated soft copper conductor of six classes stranded forming in the same way.
