Embodiment

[0069] Example: such as figure 1 As shown, a high-flexibility and high-elasticity voltage-resistant cable for new energy vehicles includes a central conductor 1, a cross-linked TPE insulating layer 2, a protective layer 3, a shielding layer and a cross-linked TPE sheath layer 4.

[0070] The central conductor is an annealed bare copper or tinned stranded conductor formed by cross regular stranding, which has high flexibility and high current carrying capacity.

[0071] The outer periphery of the central conductor is tightly covered with the cross-linked TPE insulating layer, the outer periphery of the cross-linked TPE insulating layer is tightly covered with the protective layer, and the outer periphery of the protective layer is tightly covered with the shielding layer , the outer periphery of the shielding layer is tightly covered with the cross-linked TPE sheathing layer.

[0072] The shielding layer is a double-layer shielding structure, which can greatly improve the shie...

Abstract

A highly-soft and highly-elastic voltage withstand cable for new energy vehicles comprises a center conductor, a cross-linked TPE insulating layer, a protective layer, a shielding layer and a cross-linked TPE sheath layer; the center conductor is an annealed bare copper or tin-plated stranded conductor formed by cross normal stranding; the outer circumference of the center conductor is tightly coated with the cross-linked TPE insulating layer, and the outer periphery of the cross-linked TPE insulating layer is tightly covered with the protective layer; and the outer periphery of the protectivelayer is tightly covered with the shielding layer; and the shielding layer is tightly covered with the cross-linked TPE sheath layer. The invention overcomes the cracking problem of the cable in long-term use, ensures the high flexibility of the cable, and ensures that the cable can meet the rated voltage of 1.5kv or higher, and has the performance advantages of common TPE insulation cables and XLPE insulation cables.

Description

technical field [0001] The invention relates to the technical field of new energy cables, in particular to a high-flexibility, high-elasticity and voltage-resistant cable for new energy vehicles. Background technique [0002] In the high-voltage cables for new energy vehicles, the insulation layer and sheath layer materials selected in the early stage are mainly TPE materials (thermoplastic elastomer materials). This material does not require radiation cross-linking and has advantages in production efficiency. The material mainly has the problem of cracking after long-term use. The material used in the later stage is mainly XLPE composite material (cross-linked polyethylene material), but XLPE material has disadvantages in hardness and elasticity, and its softness is not good in large square wires. [0003] To sum up, the conventional new energy wires currently on the market have the following deficiencies: 1. Poor tensile strength, generally less than 10Mpa; 2. Insufficien...
