Yes. You specify the protection relay — Siemens, ABB, Schneider, SEL. CT and VT ratios per feeder. Differential, directional overcurrent, or distance protection. Busbar differential if required. Modbus or IEC 61850 for SCADA. Our engineering team reviews your protection coordination study and configures each panel accordingly.
IEC 62271 type-test certificates from an accredited lab. CE marking. ISO 9001 quality management. We configure for regional compliance — SASO for Saudi Arabia, SNI for Indonesia, GOST for Russia. Type-test reports, routine test reports, and material traceability documents are included with every panel. Third-party witness testing at KEMA or ASTA available on request.
Routine tests per IEC 62271: circuit breaker timing, contact resistance, insulation resistance, power frequency withstand, and operation sequence verification. We also test protection relay settings, CT and VT polarity, and interlocking function. The test report ships with the panel. Factory acceptance testing with the customer present is available on request.
The VCB sits on a handcart with three defined positions: service, test, and isolated. Spring-operated mechanism charges in under 15 seconds. Vacuum interrupter bottles are sealed for life. Rated for 10,000 mechanical operations. Clear mechanical position indicator visible through the front window. Metal shutters automatically cover the busbar contacts when the handcart is withdrawn.
Both. KYN28 and KYN61 are air insulated metal-clad panels. They use atmospheric air as the insulating medium. We also supply SF6 gas insulated ring main units for compact urban substations. Air insulated switchgear costs less and needs more floor space. Gas insulated switchgear saves space at higher cost. The choice depends on your site.
KYN28-12 for 3.6kV to 12kV systems. KYN28-24 for 24kV. KYN61-40.5 for 35kV to 40.5kV. Vacuum circuit breaker on withdrawable handcart. Busbar rated 630A to 3150A. Short-circuit withstand tested per IEC 62271 up to 31.5kA.
A metal clad switchgear panel has grounded metal barriers between all compartments — busbar, breaker, cable, and LV controls. A metal enclosed switchgear uses insulating partitions that may not be grounded metal. Under internal arc conditions, grounded metal barriers contain the arc. Metal clad vs metal enclosed is a safety decision, not a naming preference. IEC 62271 defines the difference.
