Outstanding innovation points of this cable
(a) New structure: power cable, control cable, data signal cable and safety protection wire are integrated in the cable structure.
By Locomotive cable Research on the structure and use of power, control, data signal and safety protection lines, New energy cable The design structure integrating power, control, data signal and safety protection line is proposed for the first time, which solves the problem of the original single wire core and obtains the utility model zhuanli (see Annex 1-2).
(b) New process. The shielding structure solves the electromagnetic interference in technology.
Through tackling the key problem of braided copper wire shielding layer, the preparation of copper wire shielding technology for power, control, data signal and safety protection line is proposed for the first time, which solves the signal interference problem of power, control, data signal and safety protection line, and obtains a practical new-type zhuanli. (c) Application of new materials
Through the research on the insulation performance, environmental protection performance, temperature resistance and oil resistance of locomotive cables, composite polymer materials are used for the first time to solve the problems of poor volume resistivity, low dielectric strength, poor environmental protection performance and temperature resistance and oil resistance of cables, so that their volume resistivity reaches 1016 ω? cm， The dielectric strength reaches 28 mv/m. The utility model ZHUANLI is obtained.
Through the research on the release of toxic hydrogen chloride gas from chloroprene rubber, the technology of environmental protection (low smoke, zero halogen, low toxicity) in line with rohs standards, temperature resistance of - 60 ℃~+150 ℃, and oil resistance retention rate of 70% was proposed for the first time, which solved the toxicity, smoke, and halogen of toxic hydrogen chloride gas released from chloroprene rubber. The utility model of zhuanli is obtained due to the problem of temperature resistance of - 45 ℃~+100 ℃ and oil resistance of 40%.
