Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1 to Figure 2 As shown, a tensile shielded insulated cable for a charging pile includes a wire core wrapping group and a control wire core wrapping group. "Product" shape twisted, the first shielding layer 3 is wrapped outside the core package group, the core includes a conductor 1, and an inner insulating layer 2 wrapped outside the conductor 1; the core package group is composed of The advantage of twisting the three wire cores in the shape of a "pin" is that its tensile capacity is enhanced, and it will not be easily broken during frequent pulling.

[0023] The control wire core package group is composed of the control wire core 4 arranged at the center of the cable and the second shielding layer 5 ...

Abstract

The invention relates to the technical field of electric wires and cables and specifically relates to a tensile shielding insulating cable for a charging pile. The cable includes a core cladding groupand a control core cladding group. The core cladding group is formed by stranding three cores in the shape of a triangle. The outer part of the core cladding group is covered with a first shielding layer and each core includes a conductor and an inner insulating layer wrapping the outer part of each conductor. The control wire core cladding group is composed of a control wire core and a second shielding layer wrapping the control wire core. The first shielding layer and the control wire core cladding group are both wrapped with an outer insulating layer. The outer insulating layer is externally connected with and wrapped with an armor layer. A gap between the outer insulating layer and the armor layer is also filled with a flame retardant filler, and the armor layer is wrapped with an abrasion-resistant protective sleeve. The invention solves a problem that the service life of a charging pile cable, which is frequently pulled and rolled in the use process, is shortened due to the poortensile capacity and mechanical performance of an existing charging pile.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a tensile shielded insulated cable for a charging pile. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry. The product variety satisfaction rate and domestic market share both exceed 90%. In the world, the total output value of China's wire and cable has surpassed that of the United States and has become the world's largest Wire and cable producing countries. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. [0003] With the rapid development of new energy sources, the state has invested heavily in the construction of charging networks for the convenience of users. Now several large enterprises have begun to install a large number of charging piles at the ...
