Abstract
The utility model discloses a cold-shrinkable middle joint for a navaid lighting cable, which belongs to the field of the lighting cable accessories of a power transmission system. Both ends of a sheath of the middle joint are shaped like a conical cylinder, and the middle section of the middle joint is shaped like a cylinder. Shimming layers are embedded on the insulating walls of both ends of the sheath, each shimming layer is formed by a bell mouth and a straight cylinder section, and the bell mouths of the shimming layers are oppositely embedded. Since the utility model is added with the shimming layers, the field strength is uniform, and the insulation strength of the cable is enhanced. By utilizing the good elasticity, heat resistance, weather resistance and electric insulativity of silicone rubber and with a fire-retardant property and hydrophobicity, the fabricated water-proof, explosion-proof and fire-retardant airport navaid lighting cable terminal can solve the defect that the prior art cannot meet three safety requirements. The utility model has the advantages of convenient use and assembly and high reliability.
Description
Technical field
The utility model belongs to electrical power transmission system light electric cable accessories field, particularly a kind of navigational lighting aid cable shrinkage transition joint.
Background technology
For many years the airfield aid optical cable does not have special accessories, existing product all is from traditional pyrocondensation commonly used, the shrinkage annex slaps together, the pyrocondensation of exterior insulation material, cold shrink tube replaces, internal stress is handled and sealing all is to be entwined with the adhesive tape in the pyrocondensation annex, at traditional power cable at two sections cable butting places, because of little projection or pointed cone often appear in welding procedure, if with the insulating tape wrapping with bituminous seal, there is not elasticity, when often switching on, in the joint, cable core produces arc discharge with outer shielding, adopt wrapped formula, combine with cable core or cable sheathing not tight, easy watered and wetting, electric and mechanical strength is lower, be difficult to satisfy the needs of long-term safety operation, do not possess protection against the tide, safety function such as explosion-proof and fire-retardant.
Summary of the invention
The utility model is in the prior art, traditional light cable does not have elasticity, adopt wrapped formula, combine not tight with cable core or cable sheathing, easy watered and wetting, electric lower with mechanical strength, be difficult to satisfy the needs of long-term safety operation, do not possess the deficiency of protection against the tide, safety function such as explosion-proof and fire-retardant and navigational lighting aid cable shrinkage transition joint is provided, it is characterized in that two of sheath 3 is a conical cylinder, interlude is a cylinder, inlay shimming layer 2 on the insulation wall at cylinder two, shimming layer 2 is made of horn mouth 6 and direct tube section 4
Described shimming layer is on the insulation wall at cylinder two, and shimming layer horn mouth 6 inlayed in opposite directions.
Described shield bore 1 is consistent with hole size in the shimming layer.
The nozzle symmetry of described direct tube section 4 has circular arc 5.
Described navigational lighting aid cable shrinkage transition joint adopts the silastic material with elasticity, thermal endurance, weather resisteant and electric insulating quality to make.
The beneficial effects of the utility model are to make field intensity even because of adding the shimming layer, have strengthened the dielectric strength of cable.The utility model utilizes the characteristic of the favorable elasticity of silastic material, good thermal endurance, weather resisteant, electric insulating quality and has fire resistance, the hydrophobicity that does not continue burning, therefore be made into the airfield aid light cable termination of waterproof/explosion-proof/flame retardant type, thereby overcome the shortcoming that prior art can not satisfy three safety requirements.Use, easy for installation, the reliability height.
Description of drawings

Fig. 2 is a shimming layer structural representation among Fig. 1.
Embodiment
The utility model and navigational lighting aid cable shrinkage transition joint is provided.In navigational lighting aid cable shrinkage transition joint structural representation shown in Figure 1, two of sheath 3 is a conical cylinder, and interlude is a cylinder.On the insulation wall at sheath 3 two, inlay shimming layer 2, shimming layer 2 is made of horn mouth 6 and direct tube section 4, and the nozzle symmetry of direct tube section 4 has circular arc 5 (as shown in Figure 2), at the cylinder two ends, the shimming layer is inlayed in opposite directions with shimming layer horn mouth 6, and shield bore 1 is consistent with hole size in the shimming layer.
Described navigational lighting aid cable shrinkage transition joint adopts the silastic material with elasticity, thermal endurance, weather resisteant and electric insulating quality to make.
The utility model makes field intensity even because of adding the shimming layer, has strengthened the dielectric strength of cable.The utility model utilizes the characteristic of the favorable elasticity of silastic material, good thermal endurance, weather resisteant, electric insulating quality and has fire resistance, the hydrophobicity that does not continue burning, therefore be made into the airfield aid light cable termination of waterproof/explosion-proof/flame retardant type, thereby overcome the shortcoming that prior art can not satisfy three safety requirements.Use, easy for installation, the reliability height.
