Switchgear medium voltage switchgear solutions for primary and secondary distribution to suit every application. Click on the desired product type in the medium voltage one line diagram below to access the detailed product page with product information and publication library links. Medium voltage switchgear is classified by the maximum voltage it can service. Medium voltage products technical guide the mv lv transformer substations passive users 1.

12 47 kv 13 2 kv 13 8 kv and 14 4 kv. The switchgear on the low voltage side of the transformers may be located in a building with medium voltage circuit breakers for distribution circuits along with metering control and protection equipment. While medium voltage conductors are available in 90 c mv90 or 105 c mv105 ratings the actual terminations in the transformer or switchgear cable compartments are limited to 90 c. For industrial applications a transformer and switchgear line up may be combined in one housing called a unitized substation uss.

For example 15 kv switchgear maximum voltage rating is commonly applied at various actual voltages including. For all customers from system integrators to end users and all applications from refurbishment line extension to new installations.
