Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] like figure 1 As shown, a termite-proof, rat-proof, and water-blocking airport navigation lighting cable includes a water-blocking conductor 1, and a semi-conductive conductor shielding layer 2, a cross-linked polyethylene insulating layer 3, and a semi-conductive conductor are sequentially extruded outside the water-blocking conductor. The conductive insulating shielding layer 4 and the metal shielding layer 5 are combined to form a wire core; a binding tape 6 is bound outside the wire core, and a double-sided aluminum-plastic composite tape 7 is longitudinally wrapped outside the binding tape, and then an outer high-density polyethylene sheath 8 is extruded.

[0014] The water-blocking conductor 1 is formed by twisting layers of multiple wires, wherein the central wire is coated with water-blocking ointment, and the other layers of wires are longitudinally wrapped ...

Abstract

The invention discloses a termite-proof rat-proof water-blocked airport guiding lamp cable, comprising a water-blocked conductor, wherein a semi-conductive conductor shielding layer, a cross-linked polythene insulation layer, a semi-conductive insulation shielding layer and a metal shielding layer are in sequence extruded outside the water-blocked conductor to form a conductor core; a strap is strapped outside the conductor core; the outside of the strap is extruded with a high-density polyethylene outer sheath after being longitudinally wrapped with a double-sided composite aluminum-plastics tape. The cable has the characteristics of water-blocked, termite-proof and rat-proof performance, high safety and low production cost.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a termite-proof, rat-proof and water-blocking airport navigation light cable. Background technique [0002] With the large-scale construction of airports in our country, a large number of airport runway navigation lights and supporting cables are needed. Due to the need for aircraft to take off and land around the clock, in addition to radar guidance, the airport runway must have obviously stable and undisturbed light indicators to ensure that the aircraft takes off and lands accurately. In addition to runway navigation lights, it is also crucial that the supporting navigation cables have high performance and high reliability. [0003] Due to the special location of the airport, the presence of small wild animals such as hares and voles poses a threat to the reliable operation of the airport navigation lighting cables and the all-weather safe take-off and landing of aircraft. Termit...
