Abstract
The utility model provides an aluminum alloy core cross linked polyethylene insulated power cable for coal mines. The aluminum alloy core cross linked polyethylene insulated power cable comprises: at least three heat-resisting aluminum alloy conductor strand wires, each being successively wrapped by a semi-conductive conductor shielding layer, a power core cross linked polyethylene insulating layer, a power core semi-conductive insulation shielding layer and a power core split-phase metallic shielding layer from inside to outside; a cabling wrapping tape layer, an anti-flaming polyvinyl chloride spacer sleeve, an armor layer and a sheath layer wrapped on the outside of the heat-resisting aluminum alloy conductor strand wire assembly successively from inside to outside, and anti-flaming material filled between the heat-resisting aluminum alloy conductor strand wires and the cabling wrapping tape layer.
Description
Technical field
The utility model relates to a kind of rated voltage 8.7/10kV and following colliery aluminium alloy core power cable with cross-linked polyethylene insulation of being applicable to.
Background technology
Rated voltage 8.7/10kV and the following colliery that use in present domestic colliery are all to produce according to coal industry standard MT 818.13-2009 " Coal Electricity cable the 13rd part: rated voltage 8.7/10kV and following cross-linked polyethylene insulated power cable for coal mines " with the aluminium alloy core power cable with cross-linked polyethylene insulation.Cable is used for fixedly laying, and the conductor of cable is copper conductor.
Although the copper core conductor has excellent electric conductivity and mechanical and physical performance, due to the large (8.89g/cm of density of copper
3), give carrying and the mounting and installation increase larger difficulty of cable under coal mine.
According to " safety regulations in coal mine (2011 editions) " the 467th about (five) money in " downhole cable select the regulation that should observe " to fixedly laying the regulation of selecting of high-tension cable: air intake inclined shaft, shaft station and near, central substation is between working section sub station, can adopt aluminium cable.
But cable conductor adopts aluminum conductor, and larger creep easily occurs after energising and thermal cycle aluminum conductor, thereby causes bad connection, causes safety problem.Heat-resistant aluminum alloy wire (CN200910052454.2 is disclosed) manufacturing cost is lower, and all can guarantee the stability of electrical connection under high temperature and normal temperature.Therefore, rated voltage 8.7/10kV and following colliery aluminium alloy core power cable with cross-linked polyethylene insulation, preferably for air intake inclined shaft under coal mine, shaft station and near, central substation thereof to zone between working section sub station.
Summary of the invention
The purpose of this utility model is just in order to provide a kind of rated voltage 8.7/10kV and following colliery aluminium alloy core power cable with cross-linked polyethylene insulation of being applicable to.
The purpose of this utility model can be by realizing by following technique measures:
Colliery of the present utility model comprises at least three heat-resisting aluminium alloy conductor strand that are enclosed with successively from the inside to the outside semiconductive conductor shield, the crosslinked polyetylene insulated layer of power core, power core semiconductive insulation screen, power core phase-splitting metal screen layer with the aluminium alloy core power cable with cross-linked polyethylene insulation, be wrapped in successively from the inside to the outside the outer stranding belting layer of heat-resisting aluminium alloy conductor strand, flame-proof polyvinyl chloride isolation jacket layer, armour, restrictive coating, and be filled in the fire proofing between heat-resisting aluminium alloy conductor strand and stranding belting layer.
The beneficial effects of the utility model are as follows:
Cable of the present utility model can make the weight of cable significantly alleviate than copper core cable, and the price of cable also significantly reduces, and makes carrying and the mounting and installation of cable under coal mine convenient; The tensile strength of cable conductor is high, and linear expansion coefficient, creep elongation are minimum, have stable electral junction performance, make the safety and reliability of cable be far superior to the fine aluminium conductor cable.
Description of drawings
Fig. 1 is the structural representation (cross section) of the utility model cable.
Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
as shown in Figure 1, colliery of the present utility model comprises with the aluminium alloy core power cable with cross-linked polyethylene insulation and is enclosed with successively from the inside to the outside semiconductive conductor shield 2, the crosslinked polyetylene insulated layer 3 of power core XLPE type, power core semiconductive insulation screen 4, three heat-resisting aluminium alloy conductor strand 1 of power core phase-splitting metal screen layer 5, be wrapped in successively from the inside to the outside the outer stranding belting layer 7 of heat-resisting aluminium alloy conductor strand, ST2 type flame-proof polyvinyl chloride isolation jacket layer 8, armour 9, restrictive coating 10, and be filled in fire proofing 6 between heat-resisting aluminium alloy conductor strand and stranding belting layer.
