BalContact(TM) Springs for Medium- and High-Voltage Switchgear
Press release date: July 7, 2005
Able to withstand the harshest environments, BalContact(TM) Springs enable steady current transfer - even in applications where significant torquing, misalignment, vibration and/or shock are present. Spring design compensates for surface irregularities and permits wide mating tolerances, lowering production costs for spring end-users. In addition, in electrical contact applications, BalContact(TM) Springs serve as coupling rings. These allow plugs and sockets to be connected/disconnected and offer the option of a measurable holding and insertion force.
Operating parameters for BalContact(TM) Springs are as follows:
Disconnect force - 18 N
Current - 1800 A
Current pulse - 40 kA (3 sec.)
Contact resistance - R<0.01 mohm
Plug diameter - 30 mm
Spring material - Silver-plated beryllium-copper
BalContact(TM) Springs are designed for easy installation. They are available for stationary, sliding and rotary contact applications. For more information, please contact firstname.lastname@example.org; (949) 460-2100; www.balseal.com.
