Five years ago, Termate completely redesigned its insulating support range. We prioritized user needs, collaborating with designers and manufacturers across various industries, from switchboard builders to EV charging equipment makers.

The result? A range of insulators exceeding expectations in diverse applications. Made from glass reinforced flame-retardant material, they handle a wide operating temperature range and boast high mechanical strength for short-circuit fault conditions.

Termate offers a complete range of body sizes with UNC and metric inserts, ensuring compatibility with your projects. Understanding your needs, we’ve obtained UL Component Recognition for our insulators. Where applicable, they comply with UL891 Annex G‘s brace and support requirements for panelboard and switchboard accessories.
