Waukesha UZD 1030-214P Contact Arm Assembly

Description:

The Waukesha UZD 1030-214P Contact Arm Assembly is a critical switching component designed for use in Waukesha UZD® Load Tap Changers (LTCs). It functions as the movable contact arm within the selector switch assembly, transferring electrical current during tap-changing operations while maintaining reliable contact pressure and alignment. The assembly is used in transformer voltage regulation systems and is designed to withstand the demanding electrical and mechanical stresses associated with frequent tap changes. The 1030-214P Contact Arm Assembly is a key component of the 1030-027K-OEM Main Contact Arm with Rollers Kit used for UZD maintenance and refurbishment.

Applications:

The Waukesha UZD 1030-214P Contact Arm Assembly is commonly used in Waukesha UZD® load tap changers installed on power transformers in utility substations, electrical transmission and distribution networks, renewable energy facilities, industrial power systems, and power generation plants where reliable voltage regulation and continuous transformer operation are required. It is typically installed during preventive maintenance, refurbishment, and overhaul projects to restore selector switch performance, improve contact reliability, and extend load tap changer service life.
