Problems solved by technology

[0004] The current electric wires and cables are generally composed of a metal core wire covered with a plastic sheath, so their temperature resistance and pressure resistance are limited. When used in the soil layer, they are easily subjected to high pressure, which is easy to break the skin and damage the service life. affected

Embodiment Construction

[0029] The temperature-resistant and pressure-resistant cable of the present invention includes three twisted core wires 1, a mica tape layer 2 wrapped around the three core wires, and a galvanized iron layer 3 wrapped outside the mica tape layer 2, and the periphery of the galvanized iron layer 3 is extruded There is a cable sheath 4 .

[0030] Further, for rational design, the core wire 1 includes a conductive metal inner core wire 101 and a plastic skin 102 .

[0031] Further, in order to design rationally and make the electrical performance of the cable better, a plurality of second core wires 5 are arranged on the peripheral side of the above three twisted core wires, and the wire diameter of the second core wires is three times that of the core wires. The layout of the multiple second core wires 5 makes the composition of the cable closer to a circle.

[0032] The temperature-resistant and pressure-resistant cable of the present invention increases its withstand voltage...

Abstract

The invention relates to a temperature-resistant and compressive cable and production equipment and the production technology thereof. The temperature-resistant and compressive cable is characterized by comprising three twisted core wires, a mica tape layer which envelopes outside the three core wires and a galvanized iron layer which envelopes outside the mica tape layer. A cable sheath layer extrudes outside the galvanized iron layer. The temperature-resistant and compressive cable is simple in structure, reasonable in design and favorable for enhancing the temperature resistance and the compressive property of the cable.

Description

[0001] Technical field: [0002] The invention relates to a temperature-resistant and pressure-resistant cable and its production equipment and production process. [0003] Background technique: [0004] The current electric wires and cables are generally composed of a metal core wire covered with a plastic sheath, so their temperature resistance and pressure resistance are limited. When used in the soil layer, they are easily subjected to high pressure, which is easy to break the skin and damage the service life. affected.
