BalContact(TM) Springs for Medium- and High-Voltage Switchgear-The 18th China(Guangzhou)Int¡¯l Spring Industry Exhibition
10/20/2016 Spring Industry Exhibition |
--------------------------------------------------------------------------------------------------------------- |

BalContact(TM) Springs - featuring a patented canted-coil spring design enabling near-constant contact force over a wide range of working deflection - offer excellent mechanical and electrical performance in medium- and high-voltage switchgear. A small coil size and high coil count make the springs suitable for compact designs, with spring lifetime rated at > 10,000 cycles. (BalContact(TM) Springs retain their resiliency long-term, while other electrical contacts, such as leaf springs, tend to "relax" over time.) 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.
