Double-sheath towed cable with braided sandwich layer

Abstract

The present invention provides a double-sheath towed cable with a braided sandwich layer. The cable comprises an outer sheath, an inner sheath, a center reinforcement member arranged at the center of the inner sheath, a plurality of cable cores arranged around the center reinforcement member, and filling reinforcement members which are arranged in the gaps formed each to cable cores and the inner wall of the inner sheath. A braided layer formed by mixing and braiding tinned copper wires and aramid fibers is arranged between the outer sheath and the inner sheath. The cable core comprises a conductor and an insulation layer which tightly extrudes the conductor. According to the double-sheath towed cable, the braided layer allows the cable to withstand long-time winding and dragging movement, at the same time the cable has excellent tensile properties, insulation resistance, winding resistance withstand and wearing withstand. In the spool winding process, the damage of the cable by pulling force and the damage of an internal structure by spiralism generated by torsional force can be resisted. The cable is provided with the center reinforcement member and the filling reinforcement members, the effect of strengthening the entire cable structural strength is achieved, the tensile and pressure resistance ability of the cable are improved, and the durability is good.

Description

technical field [0001] The invention belongs to the technical field of cable manufacture, and in particular relates to a drag chain cable with a double sheath and a braided interlayer. Background technique [0002] Drag chain cables are widely used in reel and reel systems where cables are frequently received and released in industries such as ports, steel, mining, chemicals, automobiles, petroleum, packaging, and logistics. It is suitable for underground mining operation sites, hoisting sites, large logistics sites, port dock sites, etc. Such as: various underground mining mobile equipment, large hoisting machinery, gantry cranes, gantry cranes, bridge cranes, cantilever cranes, rocker cranes, marine grabs, garbage grabs, transportation machinery, conveyors, cable takers, mobile cranes and crane cables. , due to the continuous and frequent reciprocating winding, the towline cable laid in it is always in a dynamic winding state. Under the laying environment of thousands of...

Problems solved by technology

, due to the continuous and frequent reciprocating winding, the towline cable laid in it is always in a dynamic winding state. Under the laying environment of thousands of reciprocating movements and back and forth friction, the conductor segment core and sheath of ordinary towline cables will crack , easy aging and a series of problems
