Question

Can I sue a bolt connector with an eccentric hole in the barrel for voltage up to 35kV?

Answer

No. For voltage 35kV not only good contact matters, graduation of electrical field strength is also important as it influences the work of the connection at high voltage. Relatively big butt end edge works for smooth flow of voltage from wire to the connector, and the central symmetrical hole for even distribution of electrical field. KBT has made special series of connectors HBE-35 and СБЕ-35 that work for 20 and 35 kV. They are made of brass and are lubricated with electrical paste.
