Abstract
The utility model provides a cross-linked polyethylene insulated power cable for coal mines, which consists of a cable core and a jacket, wherein the cable core comprises three strands of conductor line cores, and the conductor line core of each strand is provided with a conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer and a copper strip shielding layer in turn from inside to outside; and the jacket is wrapped outside the cable core and provided with a filling material, a non-woven fabric belt, an inner jacket, a steel wire armor and an outer jacket in turn from inside to outside. The cross-linked polyethylene insulated power cable for the coal mines has the main characteristics of good mechanical strength, safety and reliability, and is suitable to be used as a cable for a coal mine shaft.
Description
Technical field
The utility model belongs to the cables manufacturing technical field, is specifically related to a kind of power cable with cross-linked polyethylene insulation.
Background technology
The colliery is mainly used in power cable electric power is transported to exploiting field transformer station, mobile substation, fully-mechanized mining working and high-voltage switch gear etc. from power switch room.Because it is very frequent that cable moves, it not only will be through by bending, reverse, spreading, carrying, dawdles or coal cinder is pounded to bump and waited mechanical external force, but also will stand that moisture under the mine corrodes and the burning of down-hole imflammable gas (gas).Therefore, structural design and material are being carried out when selecting with cable in the colliery, except that considering that cable has the higher electrical insulation properties and mechanical performance, also to consider to have flexibility, draftability, shock-resistant, the anti-repeatedly crooked and withstand voltage broken property of height, and having low flammability, existing colliery is difficult to satisfy above-mentioned requirements with power cable.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and the colliery that a kind of mechanical strength is good, flexibility is good, impact resistance is good power cable with cross-linked polyethylene insulation is provided.
The utility model is achieved through the following technical solutions:
The colliery power cable with cross-linked polyethylene insulation is made up of cable core and sheath, and wherein: cable core comprises three strands of conductor thread cores, and per share conductor thread core is followed successively by conductor, conductor shield, insulating barrier, insulation screen and copper strips screen from the inside to the outside; Sheath is wrapped in the cable core outside, is followed successively by packing material, nonwoven fabric belts, inner sheath, wire armoring, oversheath from the inside to the outside.
Preferably, it is stranded that described conductor adopts circle to press, and presses coefficient greater than 90%.
Preferably, described insulating material adopts the XLPE cross-linking polyethylene materials.
Preferably, described metal screen layer adopts copper strips to put up wrapped form, and the rate of putting up is greater than 5%.
Preferably, described wire armoring adopts the zinc plated mild carbon steel silk, and adopts reverse steel band colligation.
Preferably, described restrictive coating adopts ZRH-90 ℃ of PVC material of flame retardant grade.
Advantage of the present utility model is:
The colliery with the power cable with cross-linked polyethylene insulation main feature be that mechanical strength is good, flexibility is good, impact resistance is excellent, safe and reliable, be suitable for as the mine shaft cable.
