Laminated Copper and Aluminum Connectors
When flexible braided connectors are not an appropriate solution, laminated copper and aluminum connectors may be the perfect option. They maintain optimal levels of electrical and mechanical properties while sustaining the stresses of movement and heat.
As a result, laminated connectors protect your equipment and increase its operational lifespan. Using proprietary high-precision equipment, Exel manufactures laminated connectors to your specifications, and rigorously controls production quality.
Applications
Frequently used to fasten an electrical connection in extreme conditions, laminated connectors are mainly found under the following circumstances:
Low-vibration mechanisms
Minor thermal contractions and/or extensions of attached units
Low-level movement
Constrained spaces
Materials used
