Abstract

The utility model discloses a control special-type cable. A wire core is formed through the combination of dynamic wire cores and a control wire core; insulating layers are squeezingly wrapped on the exteriors of dynamic conductors so as to form the dynamic wire cores; a plurality of control conductors which are squeezingly wrapped with insulating layers are stranded and thereafter are wrapped with an aluminum plastic belt and a tinned copper wire shielding layer so as to form the control wire core; three dynamic wire cores and one control wire core are combined to form the cable core; a CPP belt is wrapped on the exterior of the cable wire; glass fiber and hemp rope are filled between the cable wire and the CPP belt; and a sheath layer is wrapped on the exterior of the CPP belt. According to the control special-type cable of the utility model which is of structural simplicity, high-temperature-resistant hybrid rubber insulating layers and high-strength wear-resistant polyurethane resin protective layers are adopted; and, the control special-type cable has the advantages of favorable heat resistance, strong corrosion resistance, excellent aging resistance, great flexibility, control special-type cable and long life service life.

Description

A control special cable

technical field

The utility model belongs to the field of electric wires and cables, in particular to a control special cable. the

Background technique

The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated overlay. Cables are widely used in various fields, especially in harsh environments such as high temperature and high pressure, the working stability of cables is particularly important. the

Utility model content

The purpose of the utility model is to provide a special control cable with simple structure, tear resistance and high temperature resistance. the

The scheme of the utility model is as follows: a control special cable, the core is composed of a power core and a control core, the power conductor is extruded with an insulating layer to form the power core, and multiple control conductors extruded with an insulating layer are stranded Then wrap the aluminum-plastic tape and the tinned copper wire shielding layer to form the control wire core. Three power wire cores and one control wire core are combined to form a cable core. The cable core is wrapped with a CPP tape. The spaces between the CPP belts are filled with glass fibers and hemp ropes, and the sheath layer is wrapped around the CPP belts. the

The insulating layer is composed of a high temperature resistant insulating layer and a high temperature resistant silicone rubber layer. the

The sheath layer is made of silicone rubber material. the

Beneficial effects of the utility model: simple structure, using high temperature resistant mixed rubber insulation layer and high strength wear-resistant polyurethane resin protective layer, has the advantages of good temperature resistance, corrosion resistance, aging resistance, good flexibility and long life. the
