Bands help Switchgear and
Instrumentation connect
Contact band technology from Icore International is playing a vital role in all withdrawable equipment produced by Switchgear and Instrumentation.
Contact band technology from Icore International is playing a vital role in all withdrawable equipment produced by Switchgear and Instrumentation, one of the world's leading manufacturers of high-specification low- and medium-voltage motor control centres and switchboards Icore's contact band, which comprises sprung contact elements intended for insertion between the fixed and moving parts of high-current contacts, is designed into the power connectors which are a key component of Switchgear and Instrumentation's withdrawable motor starters and switchgear chassis

Icore's lightweight and stainless-steel braided convoluted PTFE hoses are suitable for use with media,including oxygen, potable water, chemicals, fuel, hot oil, coolant and hydraulic fluid
The company uses the contact band in connectors with ratings up to 400A at 7.2kV, where it provides improved connection reliability, combined with lower contact resistance.
This leads to less heat being generated, and less force being required, making the withdrawable units easier to remove and replace.
"These connectors are central to the reliable operation of our equipment", said John Fallows, Switchgear and Instrumentation's Technical Director, "so we need a versatile, totally dependable and completely maintenance-free connection system.
Icore's contact bands help us to achieve this.
We have now been using them for several years, in equipment that is installed in many countries throughout the world, and we've never had a single failure associated with the bands".
Switchgear and Instrumentation originally chose the contact band from Icore because the product has a wide user base, and has proven itself to offer reliable operation throughout a virtually unlimited service life.
The contact band of the type used by Switchgear and Instrumentation is offered by Icore International in two versions.
Band 8 products have current transfer elements which are separate from the sprung supporting tape, whereas with Band 12 products, the required spring force is provided by the contact bridges themselves.
Both types provide reliable, low-loss electrical connections, with high continuous current ratings, and high short-circuit withstand capabilities.
