Braided Copper Connectors

Tinned Braided Copper Electrical Connectors and Shunts

Industrial or electrical engineers know that generators, turbines and transformers are the primary causes of vibration that affects performance at key distribution points in electrical power supplies, substations and industrial plants. Braided Copper Connectors provide a flexible electrical connection and dampen vibration.

Even with the addition of dampening pads and mounts, vibration still occurs throughout these power distribution networks, loosening lugs and other connectors attached to rigid electrical connectors like busbars and grounding bars. While upkeep and synchronization can reduce the scale of vibration from generators and turbines, ultimately the remaining vibration takes its toll over time, as loose connections result in a loss of performance, equipment failure and expansion from heat that dramatically increases the chance of fire.

 Braided copper connectors (a.k.a. flexbraid or flexible electric shunts) solve high-voltage connectivity problems created by vibration from generators and transformers. When used as the initial connector from vibration-producing equipment to a power distribution network, flexible connectors (or flexible braided jumpers) isolate the main electrical grounding bus work from the menace of vibration. And while flexible braided connectors are more expensive than using copper bus bar, copper flex braid returns the investment by cutting the potential cost of down time, maintenance and energy loss created by loose electrical connections.

In addition to the positive aspects of flex braid power shunts, the most advantageous feature of this versatile copper connector is evident in its name – flexibility.

Laminated Copper Shunts

Storm custom manufacturers copper laminated flexible shunts with resistance values on par with standard copper bar. Our shunts cover a the full range of ampacity need, serving as an ideal solution for complex installations often with minimal space. Plus laminated copper shunts are just as effective as rigid bar in preventing current imbalance and voltage loss.

ERIFLEX PVC-Coated Flexible Copper Busbar

An alternative solution for tight bends and twists associated with cabinets, switch- and panelboards...

Eriflex - flexible, insulated tinned-copper connectors.

 

Storm Power's Flexible Insulated Busbar or ERIFLEX is made of stacked tinned-copper protected by durable PVC insulation. Available in 3 meter (3000mm) lengths and other custom cut lengths, ERIFLEX is also fast and easy to install. It occupies less space, while reducing the use of excess copper, balancing the copper to current capacity by utilizing a protective, insulating PVC shield. Because the internal copper layers are free to flex within the insulation, installers are able to twist and bend the bus bar into tight spaces within circuit or panel board assemblies.

Unlike bent solid bus bar, Eri-Flex, flexible insulated bus bar can be punched or drilled after bending. All types of lug configurations are possible with less restriction to tolerances, making this remarkable bus a cost saving alternative to electrical cable with pre-set lugs.

Electrical Characteristics: Dielectric rigidity of 20 kV / mm, Voltage rated at 1000 VAC / 1500 VDC   Temperature : -32 to -131 F°

IMPORTANT! Storm can also drill or punch holes, form (bend and shape) and custom-cut ERIFLEX to any size you need.
