Manufacturing method of waterproof and moistureproof airport navigational light primary cable joint

Abstract

The invention discloses a waterproof and moistureproof airport navigational light primary cable joint manufacturing method, which comprises the following steps of S1, stripping a cable outer layer protective sleeve to expose a shielding copper sheet, and enabling the stripping length to be 6cm; s2, sleeving a copper ring of the copper braid grounding wire on the root part of the shielding copper sheet in the step S1, and fastening in place; s3, the shielding copper sheet in the step S1 is stripped, a black semiconductor layer of the cable is exposed, and the stripping length is 5 cm; s4, stripping the black semiconductor layer of the cable in the step S3 to expose the insulating layer a; and S5, stripping the insulating layer a in the step S4. The isolation transformer can solve the problems that after water is accumulated in a box body of an existing isolation transformer matched with the airport navigational light, the cable insulation resistance value is reduced due to the fact that the interior of a navigational light primary cable connector arranged in the box body is affected with damp or enters water, and the overall insulation resistance value of a navigational light loop cable is reduced; and the safety of an airport navigational light loop power supply system is influenced.

Description

technical field [0001] The invention relates to the technical field of cable connectors for navigation aid lights in civil aviation airports, in particular to a method for manufacturing a primary cable connector for airport navigation aid lights capable of waterproofing and moisture resistance. Background technique [0002] The civil airport walking aid lighting adopts the power supply mode of the whole loop cable in series, and the cable is connected with the cable connector through the cable joint, and then sequentially connected to the primary side of the isolation transformer supporting each lamp of the navigation lighting loop. The isolation transformer, cable connectors and cable splices are placed in the isolation transformer box, and the isolation transformer box is all buried around the shoulder of the airport runway and at the soil surface area of ​​the navigation lighting belt. Only the box cover is exposed, and the box body and box cover are all used Made of cast...

AI Technical Summary

Problems solved by technology

[0009] 1. The production process of primary cable joints for airport navigation lighting is not perfect, and there are obvious defects. The waterproof and moisture-proof issues are not considered in place, and it cannot effectively prevent water and moisture from penetrating into the cable core, resulting in cable insulation resistance. reduce

[0010] 2. The construction and production cable joint personnel did not carry out effective training and learning, and the production quality was poor

[0011] 3. During the post-maintenance process, the cable connector shifts back and forth, causing flexible damage to the internal protection of the cable connector

[0012] The above problems will cause water and moisture to enter the cable joint, resulting in a decrease in the insulation resistance of the primary cable for airport navigation lights.
