Description
Parameter

The VniGear550 (KYN99-12) series switchgear features a comprehensive product lineup, which greatly enriches modular solutions for systems and improves the efficiency of switchgear design. Its structural design adheres to the latest modular concept, dividing the cabinet into three main modules: the power compartment, the busbar compartment, and the cable compartment. These modules can be combined in various configurations to form different solutions tailored to specific on-site application needs.

This series offers multiple flexible solutions to meet the diverse requirements of users, ensuring reliable power distribution even in harsh operating environments. The equipment is fitted with a complete mechanical safety interlocking system, which effectively prevents operational errors and ensures safe operation. The development of the VniGear550 (KYN99-12) series is based on extensive practical operating experience with medium-voltage switchgear from our switch factories, incorporating specific user requirements from various industries. This combination of rich operational experience and innovative technology results in exceptional reliability.

Regarding its main technical parameters, the VniGear550 (KYN99-12) switchgear has a rated voltage of 7.2kV and 12kV, with a corresponding rated operating voltage of 7.2kV and 12kV. Its rated power frequency withstand voltage reaches 32kV/1min and 42kV/1min, and the rated lightning impulse withstand voltage is 60kV and 75kV. The rated frequency is 50-60Hz, with a rated short-time withstand current of up to 40kA/4s and a rated peak withstand current of up to 100kA. The main busbar rated current is 2000A, while branch busbar rated currents are available at 630A, 1250A, 1600A, and 2000A.

The protection level of the switchgear complies with both international standards such as IEC60529 and national standards like GB4208. The shell protection level is IP4X, and the internal main circuit protection level is IP67, effectively guarding against external environmental influences and ensuring the cleanliness and safety of internal components. The product design adheres to various international standards including IEC60694, IEC62271-100, IEC62271-102, IEC62271-200, and national standards like GB 3906, GB/T11022, GB 1984, DL/T 404, specifically including the technical conditions for solid insulation Q/GDW730-2012, ensuring its advanced technology and compliance. The switchgear panel color is consistently RAL7035.
