Silicone rubber insulated-sheathed high-temperature-resistant control cable

Abstract

The invention discloses a silicone rubber insulated-sheathed high-temperature-resistant control cable, which comprises a cable body and a cutting plate. The cable body comprises an inner core and an outer skin, and the inner core is formed by mutually winding a cable wire and a cotton wire. The invention relates to the technical field of control cables. When the outer skin is cut, the cable body enters a large notch; a second limiting groove cooperates with a ring rod to limit the position of the cable body; it is guaranteed that the outer skin can be cut off through the large notch position;the inner core is prevented from being damaged; similarly, when the inner skin is cut, the cable enters a small notch, the position of the cable is limited through the cooperation of the first limiting groove and the ring rod, it is guaranteed that the wire cannot be damaged while the inner skin is cut off through the small notch, and compared with a common cutter, the cutting plate and the ring rod are small in weight, small in occupied space and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to a high temperature resistant control cable with silicone rubber insulation and sheath. Background technique [0002] Control cables have the characteristics of moisture-proof, anti-corrosion and damage-proof, and can be laid in tunnels or cable trenches. The power cable is used to transmit and distribute high-power electric energy in the main line of the power system, and the control cable directly transmits the electric energy from the power distribution point of the power system to the power connection line of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6 / 1kV and above, and the rated voltage of control cables is mainly 450 / 750V. When the power cables and control cables of the same specification are produced, the insulation and sheath thickness of the power cables are thicker than those of the control cables. [0003] Wh...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-temperature-resistant control cable with silicone rubber insulation and sheath, which solves the problem that when the control cable is connected, the cutting knife for cutting the protective sheath of the control cable is difficult to accurately ensure the cutting accuracy and has a large weight. , takes up a lot of space, it is inconvenient to carry, and the material of the outer protective sleeve of the common control cable is relatively simple, and the protection effect on the control cable is not good.
