KYN61 40.5kV Armored Movable Switchgear

JUCEG is Leading KYN61 40.5kV Armored Movable Switchgear manufacturers & suppliers – offering OEM/ODM services with competitive factory pricing！The metal enclosed structure and compartmentalized design, combined with a complete interlock device, can effectively prevent accidental operation by personnel and electric shock accidents, ensuring the safety of operators and equipment. It has high insulation performance, short-circuit tolerance capacity and stable mechanical structure, which can maintain reliable performance during long-term operation, reduce the probability of faults, and lower maintenance costs. 33KV MV HV AC Metal Enclosed Switchgear can adapt to different environmental conditions and application scenarios. Through reasonable selection and configuration, it can meet the needs of various industrial and commercial fields for medium-voltage switchgear. The compartmentalized design enables each functional component to be relatively independent, facilitating maintenance personnel to carry out maintenance, replacement and testing, and also reducing the difficulty and risk of maintenance work.

Technical Specifications

Rated Voltage: 33KV, suitable for medium and high voltage power systems.

Rated Current: Depending on different application scenarios and load requirements, the range varies from several hundred amperes to several thousand amperes, such as 630A, 1250A, 2000A, etc.

Insulation Performance: KYN61 40.5kV Armored Movable Switchgear has a high insulation level and can withstand the specified power frequency withstand voltage and lightning impulse withstand voltage. For example, the rated power frequency withstand voltage (phase-to-ground) for 1 minute at the rated power frequency is up to 95KV, and the rated lightning impulse withstand voltage (1.2/50μs, phase-to-ground) is up to 125KV.

Short Circuit Tolerance: It has certain short circuit tolerance current and short circuit duration capability. For example, the rated short circuit opening current can reach 31.5KA, the rated short circuit closing current can reach 80KA, and the rated short-time withstand current and duration can reach 31.5KA/4S or 25KA/4S.
