Sandwich busducts

Sandwich busducts

A compact power path designed around the route.

Sandwich busduct systems are applied according to the approved current range, route geometry, tap-off strategy, installation conditions and project interfaces.

In short

Elins sandwich busduct solutions are engineered for efficient power delivery, reduced losses and scalable installation across commercial, industrial and mission-critical facilities.

Construction benefits

Compact sandwich construction supports controlled conductor spacing, efficient heat dissipation and reduced installation footprint.

Design and application

Riser and horizontal distribution

Switchboard-to-transformer or generator links

Data-centre and campus distribution

Industrial high-current feeders

Extendable routes for future capacity

Coordination

Routing, joint locations, supports, fire barriers, clearances and interfaces are coordinated with the building and electrical layout before manufacture.

Support

Site coordination, installation guidance, inspection and future-extension support are available as part of the lifecycle approach.

Power delivery infrastructure

High-current power distribution with reduced losses

Electrical sandwich busducts

Engineered for efficient high-current power delivery with reduced losses, improved reliability and optimised space utilisation.

Compact sandwich construction enables safer installation, lower maintenance requirements and enhanced operational performance.

Modular, extendable design supports future expansion and evolving power distribution requirements without disruption.
