8, used for connecting terminals with Cu and palms: • Always use torque wrench cer- tain the right torque achieved.8 and coarse threaded (normal thread), used with corresponding washer for connection terminals with Cu- and Al palm. SC50R50S On the SC50R50S through connector, the screws are threaded into the sleeve and can handle all their cable areas one th- read length. Installation tools can socket wrench im- pact wrench with torque force >100 Nm. This makes easier for the user to perform the installation. Handles multiple area steps The advantages shearbolt terminals are that installation can done easily without any heavy special tools and that they can manage several area steps in the same through connector/terminal, for example 10-50 mm². Shearbolt terminals are made harde- ned aluminium with alloy that allows both copper and aluminium cable be joined, while preventing the occurence of galvanic corrosion. • Always use hard flat washer reduce friction against the connection surface and the edge pressure, hardness min HB200. Through connector SC50R50S with pre-assem- bled screws. Make sure calibrated regular intervals according the supplier’s instructions. Tightening torque Recommended tightening torque for wet lubricated screws and nuts bright galvanized zinc type with strength class 8. no. no. SL70R70S-10-12 SL Shearbolt terminal 70R max mm² round conductor 70S max mm² sector conductor 10-12 screw size and thread Cat. The user gets a reduced range products and flexible solution. Labelling Elpress marking shearbolt terminals shows logo, product name, cable area (for stranded and solid conductors) and shearbolt installation order. Cat. SC50R50S SC Shearbolt connector 50R max mm² round conductor 50S max mm² sector conductor Screw and washer The following apply for bright galvanized type nuts and screws, with strength class 8. reduce the number of terminal variants, screw terminals are supplied with reduction washers that allow the use two different bolt sizes. . SC50R50S also suitable as a screen connector for 10-35 mm² Cu/Al. We recommend that the fitter uses a counterhold tool secure the shearbolt terminal more easily when tightening the screws. See table Chapter 12. It also possible use impact wrench.8:2 Shearbolt terminals Shearbolt terminals kV Elpress shearbolt terminals are available as through connectors and terminals for: • stranded and solid and cables • round cross section 630 mm² • sector cross section 240 mm² SL240N-12 The screws used are made brass, that has the advantage providing lower friction compared aluminium steel screws. The terminal palm marked with screw size M-thread for bolted joints. Use socket wrench tighten the screws. Washers are always needed for con- necting terminals with screw joints to busbars. • Install illustrated. • Use the recommended torque according to the screw manufacturer’s instruc- tions
