0.6kv and 1kv environment-friendly-type ratproof and ant-prevention power cable

Abstract

The invention relates to a 0.6kV and 1kV environment-friendly-type ratproof and ant-prevention power cable. The cable comprises three copper conductors. Each copper conductor is provided with an insulating layer so as to form an insulation wire core. A Filling is arranged outside the three insulation wire cores and a low-smoke halogen-free wrapping tape is extruded on an outer portion of the three insulation wire cores so as to form a cable core. A low-smoke halogen-free polyolefin inner sheath is arranged outside the cable core. A steel band armor layer is arranged outside the inner sheath. The steel band armor layer is a double-layer clearance-type galvanized steel strip. A low-smoke halogen-free flame-retardant polyolefin outer sheath is arranged outside the steel band armor layer. A nylon sheath is arranged outside the outer sheath. By using the cable of the invention, the structure is simple, a service life is long, heat resistance performance is good, ultraviolet ray resistance performance, oil resistance performance and chemical property resistance performance are possessed and the cable is safe and environmental-protection.

Description

technical field [0001] The invention relates to a cable, in particular to a 0.6kV, 1kV environment-friendly rat-proof and ant-proof power cable. Background technique [0002] With the development of urban construction, cable lines have a development trend from high-altitude erection to underground burial, and are more susceptible to damage from mouse bites and termites, resulting in frequent accidents such as short circuits, power outages, control malfunctions, communication, and signal interruptions. , causing great harm to society and personal property. In order to overcome the phenomenon of rat bites and ants, the outer layer of the cable is often covered with a rat-proof sheath layer. The rat-proof sheath layer is a non-toxic and environmentally friendly polyolefin sheath material added However, when the sheath layer is mechanically damaged due to transportation, underground burial construction, etc., mice or termites will gnaw and eat at the damaged place, so it will n...
