olyethylene;Sheathed conductors;Temperature;Thickness【摘要】: This part of PAS 5308 specifies requirements for and dimensions of polyethylene (PE) insulated control and instrumentation cables in multipair construction, with or without screens, and optionally incorporating a lead sheath and single wire armour.It categorizes cables into:a) type 1: PE insulated and PVC sheathed;b) type 2: PE insulated, PE bedded, single wire armoured and PVC oversheathed; andc) type 3: PE insulated, PVC bedded, lead alloy sheathed, single wire armoured and PVC oversheathed.The cables are suitable for operation at voltages up to and including 300 V r.m.s. core to earth and 500 V r.m.s. core to core (i.e. 300/500 V).These cables are not primarily intended for direct connection to a low impedance source, such as the public electricity supply.【中国标准分类号】: K13【国际标准分类号】: 29_060_20【页数】: 36P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
