Custom Medium-Voltage Bus Boots
Epoxy resin insulation boots shaped to cover medium-voltage bus joints and connections.
Insulating the Weak Points in MV Bus
Bolted joints are often the most vulnerable spots in medium-voltage bus. Exposed hardware and edges concentrate electrical stress and reduce clearances. Bus boots cover these connections with molded insulation, helping maintain dielectric integrity inside switchgear and bus duct.
When original boots are lost, cracked or no longer available, EBS produces custom epoxy resin boots that fit the actual joint geometry, so equipment can be returned to service with its insulation system intact.

Our Process
How Custom Bus Boots Are Made
- 01
Joint dimensions
We gather bar sizes, joint layout and clearance information.
- 02
Pattern design
A boot shape is developed to cover the connection fully.
- 03
Molding
Boots are produced in epoxy resin and finished for fit.
- 04
Fit check
Boots are verified for fit and access to hardware for maintenance.
Where Bus Boots Are Needed
- Medium-voltage switchgear bus joints
- Metal-enclosed bus duct connections
- Transformer throat connections
- Equipment refurbishment projects
- Replacement of cracked or missing boots
- Utility and industrial substations
Why Custom Boots Matter
- Restores insulation on joints where originals are unavailable
- Covers sharp edges and hardware that concentrate stress
- Made to fit your joint instead of a generic size
- Helps return refurbished equipment to service
Medium-Voltage Bus Boots FAQ
- What is a bus boot?
- A bus boot is a molded insulating cover placed over a bolted bus joint to insulate exposed conductors and hardware.
- Can you replace boots for older equipment?
- Yes. We produce custom boots based on the joint dimensions of existing equipment.
- Are bus boots removable for maintenance?
- Boots are designed so joints can be accessed for inspection and re-torquing when required.
