Standoff Insulators:
Manufacture:
Termate’s AM1 standoff insulator range provides excellent electrical insulation and mechanical strength for a variety of applications. Compact standoff insulators can also be referred to as pillar insulators, insulating posts, bobbin insulators, or busbar isolators.
This standoff insulator range is available in heights from 20 mm to 35 mm and insert sizes of M5 and M6. Technical data is found on the table above which displays heights, thread size and depth, maximum tightening torques, tensile and cantilever strengths, and box quantities available.
- Made from UL 94 V-0 rated, self-extinguishing material
- Halogen Free
- Operating temperature range of −40 °C to +130 °C (−40 °F to +266 °F)
- Insulation voltage of up to 1000 V AC, 1500 V DC
- Equipment voltage of up to 1000 V AC, 1500 V DC

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:
The AM1 range of standoff insulators is an important product in the Termate catalogue. Prior to entering production, the insulators were subjected to a comprehensive suite of tests that examined their electrical and mechanical performance capabilities.
All tests were conducted within industry standards and with strict quality control measures enforced throughout. This rigorous testing procedure ensures our products are always performing optimally, providing customers with reliable and high-quality insulation solutions. We take pride in providing our customers with the highest quality of products, ensuring all safety and performance requirements are met.
AM1 standoff insulators are manufactured from material that meets 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.
Our complete Standoff insulator range are UL Recognised Components, more information can be found at UL Product .
Application:
Our standoff insulators are suitable for assemblies up to 1000 V AC or up to 1500 V DC. These insulation supports provide a solution for electrical systems that need the assurance of safe and secure insulation.
In installations which require electrical isolation, they ensure that distance is maintained between two surfaces. This maintains the required level of mechanical strength and electrical insulation needed to safely contain live conductors, such as busbars. Usual installations are within:
- Battery Energy Storage Systems
- Electrical panel boards
- Control panels
- Switchboards
- EV power trains
- Power factor correction
- Distribution boards
- 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.
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.
Warranty as stated in our Terms and Conditions of Trading is void if any modification is made to the warranted product.
