KYN 28 (48 -12) armoured movable switch equipment
KYN 28 (48) - 12 armoured moving type AC metal enclosed switchgear. Electricity Department commissioned Longyuan electric power research organized by the joint design, the product should be vast power users and design units with the requirements of design and development and, accords with the national conditions, with high technical indicators, meet the GB3906 national standards and International Electrotechnical standards IEC-298 and DL402, DL403, dl404, electric power department indicators to show. Can adapt to power market development needs, and with the existing products, the introduction of competition, the product in April 1997 in Nanjing by ministerial level identification, manufacturing units and power by using the Department's attention and affirmation
Recently, KYN28 (48) -12 metal clad withdrawable switch cabinet has been widely used in electric power users.
This product is applicable to 3-12KV phase AC 50Hz single bus, double bus segmentation system, as the acceptance and distribution of electric energy use, the same structure, high safety and reliability, easy to operate and so can be widely palace in electric power, metallurgy, petrochemical and urban construction and other industries.
