A copper tape shielding control cable

Abstract

The invention discloses a copper tape shielding control cable including jackets, steel band armor, first hollow layer, a heat insulation layer, a second hollow lay and an inner wire are arranged on that outermost layer, and the sheath is coat with a steel band armored layer, the steel band armored layer is coated with a water-proof layer, the inner side of the water-proof layer is connected with the inner wire through a plurality of buffer assemblies, a heat insulating layer is arranged in the middle between the water-proof layer and the outer side of the inner wire, and a first hollow layer is arranged between the heat insulating layer and the water-proof layer. The first hollow layer arranged in the invention separates the waterproof layer from the temperature insulation layer, which prevents the heat exchange to a large extent, and the second hollow layer separates the temperature insulation layer from the inner sheath, which further prevents the heat exchange, thereby improving thetemperature insulation effect of the copper tape shielding control cable; The temperature insulation layer, the first heat insulation plate and the second heat insulation plate provided in the invention further strengthen the temperature insulation effect and improve the adaptability of the copper tape shielded control cable in the high temperature environment.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a copper tape shielded control cable. Background technique [0002] At present, PVC insulated PVC sheathed control cables are mostly used in monitoring circuits and protection lines. Because copper tape is used for shielding, the shielding effect is relatively good, and it can be laid indoors, cable trenches, pipelines, etc. where shielding is required. occasion. [0003] However, most of the current copper tape shielded control cables cannot withstand large mechanical external forces, resulting in a greatly reduced lifespan, and the temperature insulation effect is poor, and it is easy to affect the performance of the cable in a high temperature environment. Therefore, those skilled in the art provide a copper tape shielded control cable to solve the problems raised in the background art above. Contents of the invention [0004] In order to solve the technical problems in the...
