druseidt High Current Bolt Contacts consist of two equal contact halves that are fixed together. These are configured for the required bus-bar thickness before delivery. For bus-bar thickness over 10 mm, respective spacing elements are utilised. The current transfer is made over several points on the spring fed E-Cu contact bolts with a beryllium disk. The amount and layout of the contact bolts depends on the desired current load and the height of the bus-bar. Inserting the bus-bar is performed using the bar’s own weight. To guarantee effectiveness, especially in a fully automated environment, the bus-bars should be thoroughly bevelled in the contact area. The contact bolts can be quickly and easily exchanged from outside the unit. The standard version is delivered with silver coated E-Cu bolts (Part No. 50215). To increase the current transfer, especially with longer tank sessions, and to avoid abrasion these bolts are also available furnished with a soldered silver plate (Part No. 55215). The high current bolt contacts in this system are made of MS-Cast is stable and immune to interference. Bolt contacts can be connected directly to the current supply bar with no problems. The smaller contacts (up to 5000 A) are therefore available with or without the connection tabs to which e.g. flexible braided cable can be attached. druseidt high current bolt contacts are a very good alternative for any type of simple massive cast contact applications.
