Embodiment Construction

[0024] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0025] see Figure 1-2 , this embodiment provides a new polymer cable, including three cable cores 1, inner sheath 2, metal shielding layer 3, flame retardant layer 4 and outer sheath 5, cable core 1 and outer sheath There are six friction damping devices 7 in the circumferential direction between the 5, an inorganic mineral layer 6 is distributed between the cable core 1 and the inner sheath 2, and the materials of the inner sheath 2 and the outer sheath 5 are nano-doped modified polypropylene material.

[0026] In this embodiment, the nano-doped modified polypropylene material is subjected to the following tests according to the difference of each raw material component:

[0027] Trial 1: 80 parts polypropylene, 30 parts SEBS elas...

Abstract

The invention relates to the field of cable equipment, and discloses a novel high-molecular polymer cable which comprises a plurality of cable cores, an inner sheath, a metal shielding layer, a flame-retardant layer and an outer sheath from inside to outside, a friction damping device is arranged between the cable cores and the outer sheath, an inorganic mineral layer is distributed between the cable cores and the inner sheath, and the metal shielding layer is arranged between the metal shielding layer and the flame-retardant layer. The inner sheath and the outer sheath are both made of a nano-doped modified polypropylene material, the inner sheath and the outer sheath have good mechanical tensile properties, and meanwhile, the cable has an anti-vibration function through the friction damping device.

Description

technical field [0001] The invention relates to the field of cable equipment, in particular to a novel polymer cable. Background technique [0002] With the rapid development of our country's economy, the living standards of our people are also constantly improving. The most used components in electrical equipment are cables. Cables are usually twisted by several or several groups of wires (at least two in each group) A cable similar to a rope, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal energization and external insulation. The appearance of the cable can make the wire The service life is greatly increased. [0003] The material of the sheath layer of existing cables is generally cross-linked polyethylene. Cross-linking makes polyethylene change from a thermoplastic material to a thermosetting material, which c...
