UL Certified:
Our Standoff insulator range is a UL Recognised Component, more information can be found at UL Product IQ.
Manufacture:
Our insulators are made from glass-reinforced polyamide, chosen specifically for its mechanical capabilities and performance as an insulator.
Testing:
Our extensive testing procedure is designed to give you the confidence that, when correctly installed in your own assembly, our products will meet the specified ratings.
Each range has been subjected to cantilever, torque and tensile tests. Additionally they are compliant with the applicable clauses within many international standards Including those for low-voltage switchgear and controlgear assemblies, IEC 61439.
Contact us if you require compliance with other standards.
Application:
Termate insulators are commonly used in a variety of applications. They are designed to safely keep two conductive parts separated for safety reasons and to prevent contact between them that could cause damage or harm.
They are suitable for use in the manufacture of electric vehicles, battery energy storage systems, electrical panel boards and switchboards, as well as generators and drives.
Sectors:
Our standoffs are used across a variety of sectors, including power distribution, renewable energy (from wind, solar and tidal sources), the rail sector (both track side and rolling stock), in marine uses, temporary and emergency power, and also in datacentre power distribution.
