Overview
KYN28, is a type of Metal-enclosed Air Insulated Switchgear. The rated voltage can be 12kV, 24kV, and 36kV. It can be called as KYN 61 for 36kV. KYN28 can be installed with VSI or VD4 vacuum circuit breaker.
Product Details
PRODUCT INTRODUCTION
KNY28 is medium voltage switchgear with a metal enclosure, suitable for indoor installations. Metal clad and seperate the compartments from each other's. Their live parts are air-insulated. Since the switchgear is highly modular type, this make simple selection of components required by any application. The functional units of the switchgear are guaranteed arc proof in accordance with the IEC 62271-200 Standards. All the installation, operation and maintenance operations can be carried out from the front of the switchgear. The vacuum circuit breaker and earthing switches are operated from the front with the door closed. The switchgear can be back to wall installed.
