Abstract
The utility model discloses a kind of crosslinked polyetylene insulated aluminium alloy conductor underground cable, comprise cable core, filler, watertight composition, inner insulating layer, armour and sheath, described cable core has three in Chinese character pin-shaped arrangement, and described filler is arranged between two cable cores, watertight composition is extruded outside described cable core and filler, extrude inner insulating layer outside described watertight composition, outside described inner insulating layer, extrude armour, outside described armour, extrude sheath.The utility model is rational in infrastructure, can resist the adverse circumstances that underground cable faces.
Description
Technical field
The utility model relates to a kind of crosslinked polyetylene insulated aluminium alloy conductor underground cable, belongs to power cable technical field.
Background technology
Provided underground cable, higher to the requirement of cable, need to overcome rugged environment, normal cable is difficult to meet the demands.
Crosslinked polyethylene utilizes physics or chemical side's cross-linking method, makes thermoplastic polyethylene convert heat cured crosslinked polyethylene to, thus improve the heat resistance of cable, ageing-resistant performance and useful life significantly, and environmental protection.
Aluminium alloy conductor is than fine aluminium conductor economy and have excellent mechanical performance, security performance, switching performance etc.Compared with conventional copper, under the prerequisite meeting identical electrical conductance, the length of the aluminium alloy cable of identical weight is the twice of copper cable, copper conductor is replaced with aluminium alloy conductor, can cable weight be reduced, reduce installation cost accordingly simultaneously, reduce the wearing and tearing of equipment and cable.When aluminium alloy conductor contacts with air, surface can form fine and close oxide layer immediately, and this oxide layer tolerates various forms of corrosion especially.
The utility model cable uses crosslinked polyetylene insulated, and aluminium alloy does conductor, can overcome various adverse circumstances.
Utility model content
For overcoming above-mentioned deficiency, the utility model object provides a kind of crosslinked polyetylene insulated aluminium alloy conductor underground cable.
Scheme of the present utility model is as follows: a kind of crosslinked polyetylene insulated aluminium alloy conductor underground cable, comprise cable core, filler, watertight composition, inner insulating layer, armour and sheath, described cable core has three in Chinese character pin-shaped arrangement, described filler is arranged between two cable cores, watertight composition is extruded outside described cable core and filler, inner insulating layer is extruded outside described watertight composition, armour is extruded outside described inner insulating layer, sheath is extruded outside described armour, described filler is made up of traction-resistant fibre, described watertight composition is made up of waterproof insulation material, described armour is made up of steel band, described inner insulating layer and sheath are made up of crosslinked polyethylene, described cable core is by conductor, conductor shield, insulating barrier, insulation screen, copper strip shielding layer forms, described conductor forms by multiply aluminium alloy conductor is stranded.
The beneficial effects of the utility model: the utility model is rational in infrastructure, can resist the adverse circumstances that underground cable faces.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
Embodiment
Below in conjunction with accompanying drawing, utility model is described further.
A kind of crosslinked polyetylene insulated aluminium alloy conductor underground cable, comprise cable core 1, filler 2, watertight composition 3, inner insulating layer 4, armour 5 and sheath 6, described cable core 1 has three in Chinese character pin-shaped arrangement, described filler 2 is arranged between two cable cores 1, watertight composition 3 is extruded outside described cable core 1 and filler 2, inner insulating layer 4 is extruded outside described watertight composition 3, armour 5 is extruded outside described inner insulating layer 4, described armouring, sheath 6 is extruded outside 5, described filler 2 is made up of traction-resistant fibre, described watertight composition 3 is made up of waterproof insulation material, described armour 5 is made up of steel band, described inner insulating layer 4 and sheath 6 are made up of crosslinked polyethylene, described cable core 1 is by conductor 11, conductor shield 12, insulating barrier 13, insulation screen 14, copper strip shielding layer 15 forms, described conductor 11 forms by multiply aluminium alloy conductor is stranded.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification and accompanying drawing contain yet spiritual time, all should within protection range of the present utility model.
