1 rolling stock cables electricity, fuel and steam power, buses, trucks and special vehicles out of the cable needs are not the same, so the more types of these cables, but representative, during which some species are also available for other vehicles Optional. Was tendentious WISDOM HDMI CABLE stereotypes are: (1) 3kV and less natural rubber insulated cables should be screened. Save (2) 3kV and below CSM insulated cable needs. (3) 3kV and below the ethylene-propylene rubber insulated cables led to one of the series. (4) 3kV and below LSZH cable XLPE insulation led to series two. (5) 30kV EPR insulated power cables for the vehicles of special types. Then simply press TB/T1484 produced, GB/T12528 being revised. Rolling stock is the most difficult WISDOM RAC CABLE commodity LSOH crosslinked polyolefin thin-walled insulated cables. Their contents differ, there cf table in GB / T specification, can be found. 2 DC power cables urban track traffic
Light rail DC power supply, additional voltage DC 1500V and 750V. Shanghai Shentong company developed the company norms, positive cable to 1500V; negative cable to 300V, conductor cross-section of 400mm2, hard planning the first two kinds of conductor cables, flexible cables WISDOM utp cable sixth planning, cross-linked polyolefin insulation and EPDM two species, nominal insulation thickness of 2.0mm, the outer insulation should be water-repellent layer, other waterproof layer, fire layer, armor are optional plan sheath LSZH polyolefin composition data or similar composition, Nominal sheath thickness is 3.8mm. Just planning the negative cable conductor and insulation. Pilot project with the usual cable power cable simply the same.
Stranded cables are typically set by a few or several wire rope made of a similar cable insulation between each wire and often twisted around a central core, the outer package has highly insulating cover layer. WISDOM micro hdmi cables are the world's smallest standard Audio Video interconnects for hand-held consumer electronics. The hdmi micro connectors are half the size of the current Type-C (Mini) connectors, but deliver equivalent mechanical strength and electrical characteristics.
