Glenair GroundControl™ Earth Bond System
Glenair’s GroundControl™ Earth Bond System is the quickest, easiest, most cost effective solution to installing and maintaining grounding connections on steel plate and sheet metal. The GroundControl™ Earth Bond consists of two precision machined components: a stainless steel conical dowell and an electro tin plated copper bush.
The Glenair Earth Bonding system was first introduced to the Rail and Mass Transit industry for creating a secure electrical grounding system permitting passage of high current in case of electrical short circuit. The method of achieving electrical connection requiring no heat, cleaning or impact. Only a drilled hole to the required diameter and connection using a light-weight, hand hydraulic setting tool. The first requirements were for electrical grounding to steel or stainless steel materials followed by the need for grounding connections to aluminium. For steel the interface between the earth bond and grounding plate is via a tin plated copper bush and where aluminium is used the bush is manufactured from nickel-plated aluminium. As the requirement for weight reduction continues to grow and carbon fibre materials replace steel and aluminium the need to secure grounding remains paramount.
