Problems solved by technology

[0002] Communication DC distribution cables not only need to transmit electric energy, but also transmit audio signals, and the lower the inductance of the cable, the faster the cable can respond to current changes. Therefore, communication DC distribution cables require excellent low inductance characteristics, but the low inductance characteristics of the current wiring cables in the computer room are not very good, and there are still problems such as large power loss and poor audio transmission effect

Embodiment Construction

[0011] Such as figure 1 As shown, a communication DC distribution cable is composed of a first copper conductor 1, a first insulator 2, a second copper conductor 4, a second insulator 5 and a flame-retardant sheath 3, the first copper conductor 1 and the second copper conductor 4 The cross-section is the same rectangular structure, the first insulator 2 and the second insulator 5 are arranged in parallel, the cross-sectional outline of the first insulator 2 and the second insulator 5 is square, and the cross-section of the flame-retardant sheath 3 is square. The first insulator 2 and the second insulator 5 are made of ethylene-propylene rubber, and the flame-retardant sheath 3 is made of low-smoke halogen-free polyolefin.

[0012] The phenomenon that electrical signals tend to be transmitted on the outer surface of the wire is called the skin effect. In the case of the same cross-sectional area and length, the flat rectangular conductor has a larger surface area than the circ...

Abstract

The invention discloses a communication DC distribution cable which is composed of a first copper conductor 1, a first insulator 2, a second copper conductor 4, a second insulator 5 and an anti-flaming sheath 3, cross sections of the first copper conductor 1 and the second copper conductor 4 are of the same rectangle structures, the first insulator 2 and the second insulator 5 are arranged in parallel, cross section external profiles of the first insulator 2 and the second insulator 5 are square, the cross section external profile of the anti-flaming sheath 3 is square. The invention adopting this structure has better low inductance characteristic, reduces electric energy loss, ensures good signal transmission performance, is suitable for building construction characteristic of the communication machine room, is easy to mount and lay, the signal transmission is faster, and the wiring of the communication machine room is more convenient and beautiful.

Description

technical field [0001] The invention relates to electric wires and cables, in particular to a communication DC distribution cable. Background technique [0002] Communication DC distribution cables not only need to transmit electric energy, but also transmit audio signals, and the lower the inductance of the cable, the faster the cable can respond to current changes. Therefore, communication DC distribution cables require excellent low inductance characteristics, but the current low-inductance characteristics of the wiring cables in the computer room are not very good, and there are still problems such as large power loss and poor audio transmission effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a communication DC distribution cable that reduces power loss and ensures excellent signal transmission performance. [0004] To solve this technical problem, the technical solution of the present invention is: ...
