The KTE Group’s in-house KHMS fully withdrawable switchgear has been developed to provide outstanding reliability, operational safety and performance for critical power distribution applications.

Designed with high interrupting capacity vacuum circuit breakers rated up to 12kV, 3150A, and 40kA for 3 seconds, the KHMS range is fully compliant with IEC 62271-200 standards, making it ideally suited for demanding industrial, infrastructure and mission-critical environments.

The system has successfully undergone extensive testing and verification processes covering key performance and safety requirements, including:

  • Power-frequency withstand voltage testing
  • Lightning impulse withstand voltage testing
  • Main and auxiliary circuit resistance measurement
  • Main circuit temperature-rise testing
  • Short-time withstand current and peak withstand current testing
  • Verification of making and breaking capabilities
  • Mechanical operation testing
  • Protection verification
  • Internal arc testing

Operator and system safety are central to the KHMS design. Each compartment is fully segregated by metallic earthed barriers, helping protect against the electrical, mechanical and thermal effects associated with fault conditions while enhancing operational integrity and personnel protection.

Combining robust engineering, advanced protection features and full compliance with international standards, the KHMS switchgear range delivers a dependable and future-ready solution for modern power systems.
