Characteristics
Manufacture:
Our Pillar Insulators are made from halogen and phosphorus free Polyamide 6 (PA6) with low smoke emissions and flame retardant. This material has been independently tested and complies with R26 requirements of EN 45545-2:2020.
TESTING:
As with all Termate products, our Pillar Insulators have been subjected to expert testing in order to ensure suitability for their intended application. Each range is fully compliant with the applicable clauses within the international standard for low-voltage switchgear and controlgear assemblies, IEC 61439.
We can review compliance with other standards upon request. In addition, the material for this range has been historically tested for reaction to fire, opacity of smoke and toxicity of gases emitted to the withdrawn French National Standard NF F16 101/102 with a result of I3/F2 .
Our testing procedure is designed to give you the confidence that, when correctly installed in your own assembly, our products will meet the specified ratings.
Application:
Our Pillar Insulators are designed to provide insulated support in assemblies that include live conductors, maintaining the distance between two surfaces to ensure they do not touch.
Additionally, our Pillars are optimised to meet specific demands on flammability and release of particulates during a fire. They are suitable for use in;
- electronics and motors,
- underground rail rolling stock,
- tunnels,
- marine,
- mining and oil and gas applications
It is essential that you ensure our range is fully compliant with your specific requirements prior to use; our highly experienced team are available to provide more technical details and advise on product use.
