The AM6 standoff insulator range provides excellent mechanical strength and electrical insulation, making it suitable for a wide range of application. Post insulators, egg insulators, bobbin insulators, and busbar isolators are also other names for standoff insulators.
Termate AM6 standoff insulators are available in thread sizes of M8 to M16, including heights ranging from 60 mm to 100 mm. The table above list the heights, thread depths and diameters, cantilever and tensile strengths, maximum tightening torques, and box quantities.
They also possess the following characteristics:
- Halogen Free
- Relative Thermal Index ranging from −40 °C to +130 °C
- Equipment voltage of up to 1000 V AC, 1500 V DC
- Insulation voltage of up to 1000 V AC, 1500 V DC
- Made from UL 94 V-0 rated, self-extinguishing material
- UL Recognised Component; file number E505645
Termate AM6 standoff insulators are made from a halogen-free glass-reinforced material with threaded brass inserts for better corrosion resistance.
The injection moulding method, which we utilise to make the bulk of our power distribution parts, including our standoff insulators, enhances overall product quality and allows for close dimensional tolerances.
Product testing is critical for any component that will be used in an electrical or mechanical system.
Professional, thorough, and independent testing has been performed on the AM6 standoff insulator range to assure efficacy when installed correctly in their intended assembly.
Our Standoff insulator range is a UL Recognised Component, more information can be found at UL Product IQ.
One of the most widely used tests for determining the ability of plastic parts to self-extinguish after the heat source has been removed is UL 94. All Termate standoffs meet V-0 requirements for the UL 94 test standard.
Our standoff insulators have undergone comprehensive testing, including cantilever, torque, and tensile tests, to give you peace of mind that they will fulfil specified ratings when fitted appropriately.
Any component that will be used in an electrical or mechanical system must be thoroughly tested. The AM6 standoff insulator has undergone extensive, rigorous, and independent testing to ensure functionality when installed correctly in its intended application.
Our Standoff insulator range is a UL Recognised Component, more information can be found at UL Product IQ.
UL 94 is one of the most widely employed methods of evaluating the flammability and self-extinguishing ability of plastic products.
The AM6 insulator range is manufactured from material meeting the UL 94 V-0 flammability rating for plastics.
Termate insulators have been thoroughly tested, including cantilever, torque, and tensile tests, to help ensure that they meet the specific ratings when installed correctly.
AM6 standoff insulators are designed to safely and securely support and insulate busbars and other active conductors by maintaining a space between two surfaces.
They are suitable for applications up to 1000 V AC and 1500 V DC. In these types of systems, the support’s electrical insulation and mechanical strength are crucial. The following are examples of common installations:
- 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 are utilised in a variety of industries, including power distribution, rail (rolling stock and trackside), UPS (temporary and emergency power), data centre power distribution, and renewable energy.
