Characteristics
Standoff Insulators:
Manufacture:
Termate’s AU6 standoff insulator range provides excellent electrical insulation and mechanical strength for a variety of applications. Standoff insulators can also be referred to as post insulators, egg insulators, bobbin insulators, or busbar isolators.
This standoff insulator range is available in heights from 2⅜ inch to 4 inch and insert sizes of ⁵⁄₁₆″—18 to ⅝″—11 UNC. 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.
Please note that while we have referenced imperial (inch) dimensions, the height and width of the range is identical to the metric sizes. The .STEP files attached are the correct dimensions.
- Made from UL 94 V-0 rated, self-extinguishing material
- Halogen Free
- Operating temperature range of −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
- UL Recognised Component; file number E505645
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 AU6 range of standoff insulators successfully passed extensive testing to ensure their electrical and mechanical capabilities.
AU6 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.
Our Standoff insulator range is a UL Recognised Component and are listed under the product category “Panelboard and Switchboard Accessories – 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:
- Energy Storage Systems and Equipment (UL9540)
- Electrical Panelboards (UL67)
- Industrial Control Panels (UL508A)
- Switchboards (UL891)
- Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear (UL 1558)
- Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources (UL1741)
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.
Warranty as stated in our Terms and Conditions of Trading is void if any modification is made to the warranted product.
