Description
Technical field
The present invention relates to a kind of electric power ADSS optical cables anti-electrocorrosion spraying RTV process, belong to electric power ADSS optical cables
Anti-electrocorrosion technical field.
Background technology
DSS All Dielectric self-supports use loose sleeve layer strand type structure, and optical fiber is inserted in plastics Loose tube, and outer layer is high
Strength dielectric sheath.Optical cable is free of metal ingredient in itself, will not be by the side effect of high voltage magnetic field environment, can be along high voltage power transmission
The construction of line, it is widely used in power industry.ADSS optical cable installations are on high-tension line tower, through the resistance to of electric power transmission line
When opening tower, connected in technique using preformed armor rods strain hardware fitting；Because preformed armor rods is metalline, stronger high-voltage electromagnetic field ring is in
Under border, hank knotting can produce very strong induced electricity, in normal circumstances, the high voltage withstanding insulating properties of cable sheath, can ensure
Optical cable safe operation.But because air dust particle, haze pollute, cable surface filth attachment thickens, under certain condition outside hank knotting
The induced electricity at end is discharged floating dust particle, and the heat of release is burnt cable sheath, and continuous discharge can cause to spin synthetic fibre in ADSS optical cables
Because induced electricity galvano-cautery is stranded, fibre core interrupts even disconnected cable.
The content of the invention
It is an object of the present invention to provide a kind of electric power ADSS optical cables anti-electrocorrosion spraying RTV process, optical cable can be strengthened
Dielectric strength, prevent high voltage induced electricity caused by strain insulator hank knotting from discharging the floating dust that is accumulated on ADSS cable sheaths, suppress
Optical cable solves above mentioned problem present in background technology by galvano-cautery.
The technical scheme is that：A kind of electric power ADSS optical cables anti-electrocorrosion spraying RTV process, it is resistance to connecting
The preformed armor rods strain clamp component of tower, extension connecting rod, adjustable plate, RTV coating is sprayed on O-ring；The resistance to bracing cable of preformed armor rods
Clip assembly, including outer layer preformed armor rods, internal layer preformed armor rods, draw ring and U-link；The RTV coating, it is room temperature vulcanized silicone rubber
Long-acting and anti-fouling flashing coating.
The outer layer preformed armor rods, as the load terminal of ADSS optical cables, make optical cable in the case of keeping specifying sag, its
Power is no more than rated value；The internal layer preformed armor rods, for the helical layer molded line between outer layer preformed armor rods and cable outer sheath
Group, mainly play a part of transfer charge, axial tensile force can be transmitted and do not cause optical cable to distort；The draw ring, according to outer layer
The bending radius of preformed armor rods and preformed armor rods strain clamp determine the intensity and chi of draw ring to the situation of shaft tower or other fixtures
It is very little；The U-link, it is fixture between draw ring and shaft tower.The extension connecting rod, make optical cable preformed armor rods strain clamp with
Shaft tower installed position has enough bending radius；The adjustable plate and O-ring, it is convenient to adjust optical cable sag.
ADSS optical cables play high voltage induction electricity caused by the preformed armor rods of connection function under certain condition when passing through anchor support
The thick and heavy floating dust particle of cable surface is discharged, release heat is burnt optical cable, causes optical cable core segment or the phenomenon all interrupted,
By using the present invention.Technique of the spraying with high-strength insulating effect RTV coating on preformed armor rods strain clamp component, effectively
Avoid the generation of ADSS optical cable galvano-cautery phenomenons.
The beneficial effects of the invention are as follows：The dielectric strength of optical cable can be strengthened, prevent high voltage caused by strain insulator hank knotting from sensing
Electricity discharges the floating dust accumulated on ADSS cable sheaths, suppresses optical cable by galvano-cautery.
Brief description of the drawings
Fig. 1 is use state diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the invention will be further described.
A kind of electric power ADSS optical cables anti-electrocorrosion spraying RTV process, in the resistance to bracing cable of preformed armor rods of connection anchor support
Clip assembly, extension connecting rod, adjustable plate, RTV coating is sprayed on O-ring；The preformed armor rods strain clamp component, including outer layer are preformed
Silk, internal layer preformed armor rods, draw ring and U-link；The RTV coating, it is room temperature vulcanized silicone rubber long-acting and anti-fouling flashing coating.
The outer layer preformed armor rods, as the load terminal of ADSS optical cables, make optical cable in the case of keeping specifying sag, its
Power is no more than rated value；The internal layer preformed armor rods, for the helical layer molded line between outer layer preformed armor rods and cable outer sheath
Group, mainly play a part of transfer charge, axial tensile force can be transmitted and do not cause optical cable to distort；The draw ring, according to outer layer
The bending radius of preformed armor rods and preformed armor rods strain clamp determine the intensity and chi of draw ring to the situation of shaft tower or other fixtures
It is very little；The U-link, it is fixture between draw ring and shaft tower.The extension connecting rod, make optical cable preformed armor rods strain clamp with
Shaft tower installed position has enough bending radius；The adjustable plate and O-ring, it is convenient to adjust optical cable sag.
The coating that the present invention uses, without allotment during use, can directly spray for one-component coating after packing unlatching
Preformed armor rods strain clamp assembly surface is applied to, solidify afterwards film forming is contacted with the hydrone in air, ensures quality, reduces and wastes,
Construction is simple.With dry cloth by after preformed armor rods strain clamp assembly surface wiped clean before spraying, coating layer thickness should 0.25mm with
On；Surface drying in 30min, 24h are done solid work after spraying.
