Bolted connections
7.5.4.1
Material requirements
Use stainless steel bolts and nuts with the appropriate steel grade and property class for the
connection (recommended: A2-70 [designation according to ISO 3506]).
Note:
Nuts with bonded coating can be used as an alternative to uncoated stainless steel nuts.
7.5.4.2
Connection type
The following connection type is recommended when a cable lug (4 in Fig. 7-11) is connected to
a busbar:
- Spring washer (1 in Fig. 7-11) and flat washer (2 in Fig. 7-11) on each side of the busbar
(3 in Fig. 7-11).
Note:
Other washers can be used, provided they maintain the required contact pressure.
Figure 7-11: Bolted busbar connections
- Use cable lugs suitable for M12 bolts.
7.5.4.3
Lubrication
- If stainless steel bolts and nuts are used, lubricate the thread and head contact surface of
the bolt using recommended pasts, eg, Molykote D paste.
Note:
If a coated nut (eg, with bonded molybdenum-disulfide [MoS
2
] coating) is used, the
connection does not need to be lubricated.
7.5.4.4
Tightening torque
- Tighten bolted connections with bolts of sizes M10 and greater with the recommended
nominal torque for the bolt size used.
