Abstract
The utility model discloses a lighting cable used for air navigation aid in an airport. The lighting cable includes three pieces of large conductors and one piece of small conductor. The three large conductors are arranged in a triangular shape. The small conductor is disposed on an outer side of the three large conductors in parallel. The three large conductors and the small conductor are separately coated with a conductor shielding layer and an insulation layer. Taped coverings are coated on outer sides of the insulation layers of the three conductors and the small conductor. Glass fiber cloth filling ropes are disposed between the taped coverings and the three conductors and the small conductor. A piece of thin steel wire is arranged in a glass fiber cloth filling rope. The taped covering is wrapped with a principle shielding layer and a protecting bush layer successively on the outer side. In the utility model, the glass fiber cloth filling ropes are arranged between the conductors and the taped covering. The thin steel wire is arranged in the glass fiber cloth filling rope. Thus, the compactness and tensile property of the cable structure are improved. At the same time, ethylene propylene rubber is adopted in the insulation layers and the protecting bush layers, so as to enable the cable to have good electric insulativity, weather resistance and corrosion resistance.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of airport navaid and uses light conduits.
Background technology:
Power cable (power cable) is used to transmit and distribute the cable of electric energy.Be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power electric energy, comprising 1-500KV and above various electric pressure, the power cable of various insulation.
Power cable can be divided into oil-impregnated paper insulation power cable, plastic insulation power cable, rubber insulation power cable by insulating material.In can being divided into by electric pressure, lv power cable (35 kilovolts and following), high-tension cable (more than 110 kilovolts), extra-high-tension cable (275～800 kilovolts) and extra-high-tension cable (1000 kilovolts and more than).In addition, also can be divided into ac cable and direct current cables by electric current system.
The previous airfield lighting cable tensile strength and the compactedness of structure a little less than.The utility model is a kind of 3+1 core pattern, adopts three big conductors and a little conductor, and insulating barrier and restrictive coating material employing ethylene-propylene rubber to cable make electrical insulating property, weatherability and the corrosion resistance of cable increase substantially; Be provided with glass cloth gasket for packing between the conductor of cable and the lapping layer simultaneously, be provided with a finer wire in the middle of the glass cloth gasket for packing, strengthened the compactedness of the construction of cable and the tensile strength of cable.
The utility model content:
To the prior art problem; The purpose of the utility model provides a kind of airport navaid and uses light conduits; Be applicable to that airfield aid light transmission system voltage withstand class requires 6KV, long-term work are not more than 90 ℃ condition in ambient temperature under, the compactedness of structure and the tensile strength of cable are greatly enhanced.
The technical scheme of the utility model is following:
The airport navaid is used light conduits; Comprise three big conductors, a little conductor; Three big conductors are arranged in a triangle; A little conductor of three big conductor parallel placements in the outside, described three big conductors and a little conductor outside are enclosed with conductor shield, insulating barrier respectively successively, and the insulating barrier outside of described three big conductors and a little conductor is enclosed with lapping layer; It is characterized in that: be provided with glass cloth gasket for packing between described lapping layer and three big conductors, a little conductor; The cross section of glass cloth gasket for packing is the curved triangles in three limits, is provided with a finer wire in the middle of the described glass cloth gasket for packing, and the described lapping layer outside is enclosed with total screen, restrictive coating successively.
Described airport navaid is used light conduits, it is characterized in that: described thickness of insulating layer is 3.8-4.2mm, described restrictive coating thickness 3.4-3.8mm.
Described airport navaid is used light conduits, it is characterized in that: described insulating barrier, restrictive coating material adopt ethylene-propylene rubber.
