CT Busbar Supports – Electrically Insulating Busbar Clamps and Braces

CT Busbar Isolators are electrically insulating busbar supports, clamps and braces that hold copper or aluminium busbars securely within an enclosure. Available as CJ-50, CT2-20, CT4-30, CT4-40, CT4-50 and CT5-25, they suit low, medium and high voltage switchgear assemblies.

Why Choose the Busbar Isolators

Busbars must be held firmly and kept at safe distances from each other and from the enclosure. Busbar Isolators provide that support while preventing electrical discharge.

Made from BMC and SMC moulding compounds, they perform in temperatures from -40 to 140 degrees Celsius.

Installation and Setup Tips

Only trained operators should use hydraulic busbar tools. Check hoses, fittings and oil level before each session, never exceed rated pressure and keep hands clear of dies and blades. Release pressure before changing dies or disconnecting hoses, and wear safety glasses and gloves during operation.

How to Choose Busbar Processing Equipment

Busbar work usually involves three operations: cutting, punching and bending. Check the maximum width and thickness of the bars you use, and choose tools with enough force for copper and aluminium at those sizes. Decide on the power source, an electric pump for workshop volumes or a pedal pump for portable site work, and make sure hoses, connectors and valves are compatible across tools. Keeping spare dies, blades and seals avoids downtime.

Maintenance and Care

Use the recommended hydraulic oil, keep couplings clean and capped when disconnected, and inspect hoses for wear or leaks. Clean dies and blades after use, replace worn parts early and follow the service intervals in the manual. Good maintenance keeps hydraulic tools safe and precise for years.

Setting Up an Efficient Busbar Workshop

Arrange cutting, punching and bending stations in sequence so bars move smoothly from stock to finished part. One electric pump can serve several tools through quick connectors, while a pedal pump is useful for site work. Keep dies, blades and seals organised by size to reduce setup time.

Why Precise Busbar Fabrication Matters

Clean cuts, accurate holes and correct bends make busbar joints fit perfectly, which keeps contact resistance low and prevents hot spots in switchboards. Professional hydraulic tools deliver this precision repeatedly, improving both safety and panel build quality.
