Frequently Asked Questions
What voltage levels does this switchgear cover?
This range covers 11kV, 24kV and 33kV medium voltage distribution. Share your system voltage and short-circuit level and we will confirm the appropriate rating.
Is the switchgear metal enclosed?
Yes, metal enclosed designs including KYN28 and KYN61 withdrawable types are available, together with air insulated configurations. The choice depends on your layout, maintenance approach and budget.
Can the protection scheme be customised?
Yes. Circuit breaker type, protection relay, interlocking, metering and communication interface are selected against your protection coordination study and project specification.
Which standards does it comply with?
Switchgear is designed to IEC 62271-200 and the GB equivalent. Where your project specifies another standard, confirm the applicable clauses before production starts.
What do you need to provide a quotation?
System voltage, rated current, short-circuit rating, number of panels, breaker and protection requirements, and your single line diagram.
