Problems solved by technology

[0004] Although this kind of airport navigation light cable has good shielding effect, excellent anti-interference performance and insulation performance, the all-round waterproof technology ensures that the cable can be used safely in rainy weather and water. When the cable fails, it can be well grounded and the allowable short-circuit current is large. , safe to use, suitable for airport navigation light cables, but often the cables are in areas with relatively harsh environments, and the temperature difference between day and night is usually large, which greatly reduces the service life of the cables

Abstract

The invention discloses a novel cable protection device and aims at providing a cable protection device for reducing temperature difference. The advantages of that technical scheme are as follows: thecable includes an inner core, a protective layer is wrapped around the inner core, a loss prevention device is also arranged outside that protective layer, the loss prevention device comprises a protective sleeve arranged outside the protective layer, a groove on the surface of the protective layer, a bearing nested in the groove and connected with the groove through a sliding device, an externally threaded connecting ring located outside the bearing, a connecting port threadably connected with the connecting ring at the top of the protective sleeve, a sponge ball arranged in the protective sleeve, a plurality of through holes arranged on the surface of the protective sleeve and a water-proof permeable membrane arranged in the through holes. The sliding device comprises a sliding path arranged on the inner walls of the grooves and a sliding block arranged on inner ring of the bearing and clamped to the sliding path.

Description

technical field [0001] The invention relates to the field of cable equipment, in particular to a novel cable protection device. Background technique [0002] Derivatives / new products of wire and cable are mainly due to application occasions, different application requirements for cables, equipment convenience, and equipment cost reduction requirements. New materials, special materials, or changes in product structure, or improved process requirements, or Produced by combining different types of products. Different materials are used such as: flame-retardant cables, low-smoke zero-halogen / low-smoke low-halogen cables, termite-proof, mouse-proof cables, oil-resistant / cold-resistant / temperature-resistant cables, etc. [0003] At present, the Chinese patent with the publication number CN203910315U discloses an airport navigation lighting cable, which includes a semiconducting resistance water layer, a conductor shielding layer, an insulating layer, and a semiconducting resistan...
