集团电气规范要求

1Each breaker should be able to be locked and tagged out.

每个断路器都应能被挂牌上锁。

防松弹性星角垫片应该用于紧固螺丝用，例如母排，接头，电缆和母排之间的接头。如有需要在母排上打孔则要求在该位置加上一块同等尺寸的铜排。

4All the applied nuts, washers, bolts etc should be from compatible material to prevent upon galvanic corrosion

2Spring/star type of washers should be used for everything that is bolted down, such as bus-bar tie-ins, cable-lug

3An extra piece (same size) of bus bar would be used when something needs to be bolted down to eliminate the ca

所有用到的螺母、螺栓等应是兼容的材料，以免腐蚀。

5Proper torque wrenches should be used for everything that is bolted down.

应使用合适的力矩扳手固定所有的螺栓。

6At least two spare threads at the bolt/nut should be visible for everything that is bolted down, after tightening wi所有的螺栓/螺母在用力矩扳手固定后应至少露出两圈螺纹。

7The bus-bars' cupper purity should be > 99.95% and complies at least with local (or better) norms for manufact铜排的铜纯度应大于99.95%且符合国标的规定。

8Hot-shrink insulation sleeves should be used for all down-stream bus-bar systems.

热缩绝缘管应被用于所有的下引母排。

9Everything within the panels is made of fire retardant material, including internal wiring (fire retardant class A)配电盘内的所有材料都应该是防火材料制成的，包括内部线缆（防火A级的）

10Two wire/conductors as maximum is used per cable-lug, making sure each wire/conductor is in direct contact w每个电缆接线头（线鼻子）最多只能压两根线，确保每根线都和相关的电缆接线头直接接触（最好的11Nude bus-bars/connections are at least 20-25mm away from other nude metal/bus-bar parts etc to prevent upon 裸露的母排之间，或与裸露的金属部分等的安全距离一定要在20--25mm ，目的阻止电弧故障12Cabinets should be thought of as ‘2-dimensional’- i.e. components would be mounted upon the back p配电柜应该被理解成2维的，也就是说部件都要安装在一个平面的背板上

13Panel bottom plates could be removed easily in order to prepare holes for corresponding cable-gland entries conv配电盘底部应该可以很容易的移开，这样做可以使相关的电缆旋紧件很方便14IP31 is set as a minimum for corresponding panels.IP31是我们最低的防护等级要求

15All cabling/wiring stays within minimum bending radius所有的电缆一定要保证它们在最小弯曲度内。

16Supplier's QC procedures, designs etc do comply with all applicable local and IEC norms and standards.供应商的质量认证证书，设计等等一定要和本地要求和IEC的规范相符

17Field cabling should be terminated conveniently, there should be sufficient space below corresponding terminal b接线要合理，我们要保证接线端子的下部至少100mm的接线距离
