Class A system - any phase conductor of such A system can be separated from the system within 1min when it comes into contact with ground or ground conductors. B class system, the system includes only the single-phase earth fault short-time running conditions, earth fault time should be no more than 1 h, but in any case, the longest do not exceed 8 h, ground fault total duration of not more than 125 h every year; Class C systems -- systems that do not belong to class A and class B.

In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 6/10 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status.

业主在水电改造之前要和施工方商量好价格问题,细致到一根管里穿两根线和穿一根线的价格,一个暗盒多少钱等。水路方面通常来说,大多数施工方在施工完毕后才告诉你一根管穿两根线的价格和两个一管一线的价格一样。也就是说如果开槽埋管,里面一根线是30元/米,而同样开一个槽,里面同样只放一根管,只是管里有两根线,但价格却是60元/米了。这样随随便便就能让多花上千银子。显然这样的计费方法是不合理的,一根管穿两根线时,开槽和穿线管的成本都是一样的,只应该加上多的那根线的费用。

Flame-retardant cable classification: according to the different flame-retardant materials of cables, flame-retardant cables are divided into halogen flame-retardant cables and halogen-free low-smoke flame-retardant cables. Which contain halogen flame retardant cable insulation, sheath, outer sheath and auxiliary material (package belt and filling) in whole or in part by polyethylene (PVC) containing halogen flame retardant material, thus has good flame retardant properties. However, when the cable burns, a large amount of smoke and haloic acid gas will be released. Haloic acid gas is corrosive to the surrounding electrical e When the cable burns, it will cause harm to the surrounding electrical e and rescue personnel, which is not conducive to the fire fighting and rescue work, thus causing serious "secondary hazards". All or part of the insulation layer, protective sleeve, outer protective layer and auxiliary materials (packing belt and filling) of the halogen-free low-smoke flame-retardant cable are adopted

下面这起电工违章触电死亡的真实案例,为我们的电气维护工作敲响了警钟。我们不禁反思:这样的违章,我们自己或身边的有没有?这样做“好事”到底值不值得?某年9月,湖南某电业局按计划开展10千伏Ⅱ段部分设备年检工作,负责清扫工作的作业人员,在完成5个间隔的开关柜(后柜柜内)小车清扫工作后,自行走到屏后,移开拦住3×24TV后柜门的安全遮拦,用放在地上的专用扳手卸下3×24TV后柜门2颗螺丝,打开后柜门准备进行清扫,开关柜内带电母排B相对其放电,经抢救无效于死亡。
