Anti-compression round control cable

一种抗压圆形控制电缆

Abstract

The utility model discloses an anti-compression round control cable which comprises main conductors, control conductors and a cross rubber skeleton. An outer side of each main conductor and an outer side of each control conductor are both covered by a polyimides insulating layer. The plurality of control conductors and one main conductor are twisted and then are covered by a multi-layer mineral wrapping strip material overlapped wrapping layer, an oxygen ambient silica layer and a semi-conductive resin shielding layer in sequence, so that a round control core is formed. Four right-angle gaps of the cross rubber skeleton are respectively provided with two round control cores. An outer side of the cross rubber skeleton is sequentially covered by a tinned steel wire woven layer, a thermal insulation layer and a low-smoke halogen free polyolefin oversheath. The thermal insulation layer is internally provided with silica gel. Four ends of the cross rubber skeleton are respectively provided with an adhesive agent. The four right-angle gaps of the cross rubber skeleton are respectively provided with the two round control cores, so that the anti-compression round control cable is simple in structure, reasonable in design, thermal-insulation, insulating, good in shielding effect, stable and reliable.
本实用新型公开了一种抗压圆形控制电缆,包括有主导体、控制导体和十字形橡胶骨架,所述的主导体和控制导体外侧均包有聚酰亚胺绝缘层,将多个控制导体和主导体绞合后外侧依次包覆有多层矿物包带材料重叠绕包层、氧化硅层和半导电胶屏蔽层构成圆形控制线芯,在十字形橡胶骨架的四个直角空隙中分别放有两个圆形控制线芯,在十字形橡胶骨架外侧依次包覆有镀锌钢丝编织层、隔热层和低烟无卤聚烯烃外护套,在隔热层内部设有硅胶,在十字形橡胶骨架的四个端部分别涂有粘连剂。本实用新型在十字形橡胶骨架的四个直角空隙处分别设有两个圆形控制线芯,结构简单,设计合理,隔热、绝缘、屏蔽效果好,稳定可靠。
