* Fixing details: Hole diameter = Standoff thread size [M]+1 mm. e.g. M6 Thread = 7 mm hole diameter.
** Tensile and Cantilever Strength figures are based on tests carried out at normal room temperature, nominal 23 °C.
Our Insulators have ISO M inserts with coarse threaded inserts in accordance with BS 3643-2 – Table 1 and ISO 262
Our metric insulators can be converted into Male/Male or Female/Male versions by fitting studs from our Grub Screw Pack.

Our standoff insulators are made from a halogen-free glass-reinforced material, which was specifically chosen for its mechanical and electrical insulation properties.
Brass inserts are used due to this alloy’s resistance to corrosion. The injection moulding process, combined with our excellent quality control and inspection procedures, results in a consistent product across every production run.
Testing:
Termate carries out rigorous and appropriate testing on all our products. The AM2 range of standoff insulators undergone extensive testing to ensure their electrical and mechanical capabilities.
AM2 standoff insulators meet the requirements for UL 94 V-0. UL 94 being a standard for the safety of flammability of plastic materials for parts in devices and appliances released by the Underwriters Laboratories.
The insulating stand off range is also fully compliant with the applicable clauses within the international standard for low-voltage switchgear and controlgear assemblies, IEC 61439.
Our Standoff insulator range is a UL Recognised Component, more information can be found at UL Product IQ.
Application:
Our standoff insulators are suitable for assemblies up to 1000 V AC or up to 1500 V DC. They are intended to safely and securely support and insulate busbars and other live conductors by maintaining a distance between two surfaces. In these types of installations, the electrical insulation and the mechanical strength of the support are paramount. Usual installations are within:
- Battery Energy Storage Systems
- Electrical panel boards
- Control panels
- Switchboards
- EV power trains
- Power factor correction
- Distribution boards
- Generators
- Switchgear
- Controlgear
- Drives, inverters and converters
These electrical installations can be found in a wide range of sectors including power distribution, rail (rolling stock & trackside), renewable energy, UPS (temporary and emergency power), and data centre power distribution.
At Termate, we have been designing and manufacturing electrical insulating parts and components, such as our standoff insulators, from our Nottingham UK based factory for over 60 years. Quality is ensured on every product we produce. Our knowledge and experience of the raw materials used, the performance requirements, and the application of our products allow us to provide products that are safe and fit for purpose.
Termate is committed to the highest standard of customer focus and we have made every effort to maintain the accuracy and completeness of the information provided in this data. Where improvements to our products affect their installation and usage we endeavour to contact any customers who may be affected.
