Trusted Visible Load Break Transformer manufacturer & dealer
SkyPower designs and supplies Visible Load Break Transformers in Canada that deliver reliable, efficient, and safe power distribution for utilities, industrial facilities, and renewable projects. Each transformer is engineered to meet CSA and cULus requirements, ensuring durability and performance under Canada’s harsh environmental conditions.
Remanufactured & new units to fit your project
Skypower offers Visible Load Break Transformer (VLBT) integrates a load break switch with a mechanical viewing window, allowing operators to directly verify the open or closed position of the switch for enhanced safety and operational control. This design eliminates uncertainty during field operation, ensuring quick, reliable isolation and switching under standard medium-voltage distribution conditions.
The visible window provides clear mechanical indication of the switch state, while a gang-operated handle ensures simultaneous operation of all phases. Configurations are available in 2-position and 4-position variants to support both loop-feed and radial-feed distribution systems. Each unit is engineered and tested for consistent performance in Canadian utility, commercial, and industrial applications.Visible Break Transformer Standard Specification
