Background

A smart energy OEM in the United States required a custom power cable assembly with strict safety certifications for home electrification applications.

The Challenge

The 2AWG 3-conductor cable faced diameter and flexibility issues, and an initial material substitution โ€” flame-retardant tape for the inner jacket โ€” was rejected by the customer. It failed to meet the mandatory TYPE TC-ER certification required for both inner and outer jackets.

Our Solution

We collaborated directly with the raw cable manufacturer to engineer a compliant inner- and outer-jacket material combination. The combination met the TYPE TC-ER standard while achieving the target diameter and flexibility specifications.

The Result

We delivered a compliant technical specification that satisfied the customer's mechanical engineering team. The approval kept the project on its trajectory toward high-volume production.
