The utility model is by being arranged tension shielding layer, the prefabricated tension filling in center so that cable tensile strength and resist bending Performance improves, can fast move or automated system that job area is big in make as power transmission or control signal transmission With the mechanical arm being more suitable in mobile device, hanging device, industrial robot has excellent anti-interference, resistance to torsion Turn, the characteristics such as resist bending, the requirement in market can be met.

Insulated electric conductor described in the utility model is made of conductor and insulating layer, and the insulating layer is wrapped in outside the conductor, The insulating layer is made of modified silicon rubber, and the conductor is twisted by ultra-fine soft copper monofilament, and copper is woven outside stranded copper monofilament Silk forms knitted conductor.

The utility model insulation uses modified silicon rubber reinforcement material.When insulated wire cores bend, reinforce silicon rubber Insulating materials can be consistent with the deformation of copper conductor, avoid the generation of copper wire crack conditions；It twists in insulated wire cores When, there is very wide regime of elastic deformation because reinforcing silicone rubber insulation material, can crack now because of torsion to avoid insulation occurs The generation of elephant.Improve the service life of cable.After thering is conductor to select ultra-fine soft copper monofilament twisted again, outermost layer proof copper-wire braided Into knitted conductor.The tensile strength and resistance to bend(ing) energy for improving conductor, ensure that cable is reduced during normal use The generation of fracture accident.

Liner layer described in the utility model has thermoplastic polyester elastomer to be made.Liner layer uses thermoplastic polyester elastomer Material（TPEE）, in the gap after making thermoplastic polyester elastomeric material fill to stranding between cable core, make core position more Stablize, avoids that play occurs during cable moves use.

External sheath layer described in the utility model is made of conjugated polyether ester elastomer.Oversheath uses copolyether fat elastomer material Material（TPEE）, elastomeric material（TPEE）With excellent weatherability, there can be wear-resisting, resisting salt fog corrosion, mould proof, resistance to simultaneously The characteristics such as damp and hot, chemically-resistant solvent, resistance to mineral oil and fuel oil.

Tension shielding layer described in the utility model includes proof copper-wire braided shielded layer, tensile layer, and the tensile layer uses Du Pont Fibrage is outside the proof copper-wire braided shielded layer.To having the occasion of anti-interference requirement, cable design proof copper-wire braided shielded layer.For The whole tensile strength for improving cable weaves one layer of tensile layer again on the outside of proof copper-wire braided shielded layer using DuPont fibrids.This screen The setting for covering layer+tensile layer, the tensile strength than the shielding of conventional proof copper-wire braided is big, while more resistant to bending, can preferably use It is used in frequent bending.

The prefabricated tension filled layer in center described in the utility model is co-extruded by DuPont fibrids and polyethylene foamed.It is this to set It sets so that the tensile strength of cable greatly improves, while milk is bent, and preferably can be used to be frequently bended use.
