[0002] With the development of industry, agriculture and science and technology, especially the needs of military industry, radio pulse technology has been widely used in various electronic equipment such as radar, television, remote control, telemetry, multi-channel communication and electronic computers. In addition, high-voltage pulse technology is also widely used in atomic energy industry plasma physics and accelerator technology. In order to transmit the pulse generated by the pulse generator to various equipment loads, cables are used to connect them in the middle. High-voltage pulse cables are specially used to transmit various high-voltage pulses. At present, the DC pulse high-voltage cables on the market are mostly improved in terms of functions and other aspects. The use environment of such products is harsh. During the installation and operation process, they are often subjected to various mechanical external forces such as dragging, pulling, grinding, bending, smashing or squeezing, which can easily damage the cable skin and expose the internal battery core, shorten the service life and make the cable too heavy, which is not convenient for workers to transport and install the cable. Therefore, a DC pulse high-voltage cable is proposed to solve the above problems. However, due to its use characteristics, the high-voltage power cable is relatively thick, basically above 35mm2, and there are problems such as unequal connection and large bending radius, which are not suitable for the use requirements of special equipment.

During installation, a protective layer is connected to the outer surface of the wrapped pipe to protect the wrapped pipe. The protective layer is used to protect the wrapped pipe and the battery cells inside the wrapped pipe, and protect the cable from mechanical damage and various environmental factors during laying and operation. The protective layer includes a stainless steel mesh sleeve. The stainless steel mesh sleeve has good softness, is dust-proof and rust-proof, and is resistant to compression, tension, and wear, and provides excellent electromagnetic shielding. Connecting the stainless steel mesh sleeve to the wrapped pipe can make the wrapped pipe have good wear resistance, and even if the cable skin is damaged, the stainless steel mesh sleeve will not be damaged and the battery cells will not leak out.

[0005] The battery core includes a conductor, which is used to transmit current. An insulating layer is provided on the conductor to insulate the conductor.
