Abstract
The present invention relates to a kind of construction of cable for the laying of 500kV underground substations, the structure includes the cable group being made up of the cable of a plurality of Orthogonally arrangement, the fixture being arranged between a plurality of cable and the cable block for being arranged on cable group upper and lower surface, described cable block is arranged on the cross bar of cable bearer, and is bound by band.Compared with prior art, the present invention has the advantages that anti-wear, installation is firm.
Description
Technical field
The present invention relates to underground substation cable laying field, is applied more particularly, to one kind for 500kV underground substations
If the construction of cable.
Background technology
With developing rapidly for social economy, all trades and professions are all constantly increasing to the demand of electric power, Shanghai Urban center
Area's power load more crypto set.In order to ensure the safe and reliable electricity consumption in downtown area, properly settle such regional land used it is nervous,
The siting of station is difficult, soil is expensive, the costly Construction Problems brought of earth clearance, is integrally required with reference to area planning, is
Land utilization ratio is improved, improves urban landscape, Optimizing City environment, underground substation is arisen at the historic moment.
Due to needing to lay more cable in underground substation and ground is moister, so being necessarily placed at cable trough
On, and be fixed by the way of band or metal button member binding compress, but because binding excessively fastens so that cable
Pressure between the cross bar of cable trough and between band and cable increases, and increases friction and is easily damaged cable, causes accident
Occur.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of anti-wear, installation surely
Solid be used for 500kV underground substations laying the construction of cable.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of construction of cable for the laying of 500kV underground substations, the structure include the cable by a plurality of Orthogonally arrangement
The cable group of composition, the fixture being arranged between a plurality of cable and the cable block for being arranged on cable group upper and lower surface, it is described
Cable block is arranged on the cross bar of cable bearer, and is bound by band.
Cable in described cable group is twisted polyethylene cable.
Described twisted polyethylene cable include set gradually from inside to outside conductor, internal shield, insulating barrier, external shield
Layer, rubber strip, ripple aluminium sheath and PVC oversheaths.
Described fixture is star PVC products, and its surface is provided with anti-slip veins, and is close to cable outer surface.
Described cable block includes upper cable block and lower cable block, and described cable group is close to be arranged on cable block, consolidated
Determine in the space that part and lower cable block are formed.
The upper surface of described upper cable block is provided with horizontal groove, and does cure process in groove surfaces.Described
The lower surface of lower cable block is provided with a plurality of anti-skidding ripple.
Compared with prior art, the present invention has advantages below：
First, it is anti-wear：The upper and lower surface of a plurality of cable of the present invention is provided with the cable block being adjacent to therewith, lower cable block following table
Face is provided with anti-skidding ripple, prevents cable bottom from being worn with cross bar, upper cable block upper surface is provided with case-hardened groove, to put
Band or fastener are put, effectively reduces pressure and friction to cable.
2nd, installation is firm：The present invention is provided with star PVC fixtures, its outer surface and cable between the cable of Orthogonally arrangement
It is close to set, prevents that the position between cable is mobile and rubs.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1st, cable, 2, fixture, 3, cable block, 31, upper cable block, 32, lower cable block.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：
As shown in figure 1, the present invention provides a kind of construction of cable for the laying of 500kV underground substations, the structure includes
The cable group that is made up of the cable 1 of a plurality of Orthogonally arrangement, the fixture 2 being arranged between a plurality of cable 1 and it is arranged on cable group
The cable block 3 of upper and lower surface, cable block 3 is arranged on the cross bar of cable bearer, and is bound by band.
Cable 1 in cable group is twisted polyethylene cable, and the twisted polyethylene cable includes setting gradually from inside to outside
Conductor, internal shield, insulating barrier, external shielding layer, rubber strip, ripple aluminium sheath and PVC oversheaths.
Fixture 2 is star PVC products, is adapted to the shape of cable surface, and its surface is provided with anti-slip veins, and and cable
It is close to 1 outer surface.
Cable block 3 is plastic cement product, including upper cable block 31 and lower cable block 32, cable group are close to be arranged on cable block
31st, in the space that fixture 2 and lower cable block 32 are formed.
The upper surface of upper cable block 31 is provided with horizontal groove, and does cure process in groove surfaces, lower cable block 32
Lower surface is provided with a plurality of anti-skidding ripple.
Multiple and ft connection heat emission hole is further opened with upper cable block 31 and lower cable block 32, prevents cable heat
It is too high, cause the accident.
