Environment-friendly and tough insect-resistant semi-conductive cable

Abstract

The invention discloses an environment-friendly and tough insect-resistant semi-conductive cable in the technical field of insect-resistant ant semi-conductive cables. An aluminum alloy armoring tapeis fixedly arranged on the inner surface of a buffer water-blocking strip. An isolation sleeve is fixedly extruded on the inner wall of the aluminum alloy armoring tape. Three main copper conductors of the same structure are nested in the inner cavity of a wrapping belt. An inner semi-conductive shielding layer is fixedly extruded on the outer wall of each main copper conductor. An insulating shielding layer is fixedly extruded on the outer wall of each inner semi-conductive shielding layer. An outer semi-conductive shielding layer is fixedly extruded on the outer wall of each insulating shielding layer. A cross-linked polyethylene insulating layer is fixedly extruded on the outer wall of each outer semi-conductive shielding layer. A secondary copper conductor is nested between adjacent two cross-linked polyethylene insulating layers. An inner sheath is fixedly extruded on the outer wall of each secondary copper conductor. The hardness and compressive strength of the cable are improved. The cable is insect-resistant. The protectiveness of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of insect-proof semi-conductive cables, in particular to an environment-friendly and strong insect-proof semi-conductive cable. Background technique [0002] With the continuous development of cities and industrialized cities, the demand for electricity continues to increase, and cables are becoming more and more popular. However, in areas where there are more regional termites and rodents, ordinary materials are easily damaged by termites or rats. , As a result, the moisture in the external environment can easily enter the inside of the cable, so the cable needs to have better anti-termite ability. Because the environment where the cable is located is relatively harsh, it needs to have a strong hardness to prevent sharp objects from scratching the cable and causing copper core Leakage is a potential safety hazard. For this reason, we propose an environmentally friendly and strong anti-insect semi-conductive...
