LOW VOLTAGE STANDOFF INSULATORS 

Low voltage insulators provide insulated support in assemblies that include live conductors. They maintain the distance between two surfaces, preventing them from touching. Standoff insulators generally have threaded metallic inserts at each end to allow them to be bolted to components within the assembly. The moulded material of the insulator is chosen for both its insulating and mechanical properties, with the part designed to ensure that the material separates the inserts to stop any current flowing. 

Termate standoff insulators are sold globally to panel builders manufacturing electrical panel boards, control panels, switchboards, power factor correction and distribution boards, as well as component manufacturers of generators, switchgear, controlgear and drives. In these applications, standoff insulators are commonly used to hold busbars (conductors) off from enclosure walls and other surfaces.  Our standoff insulators have an insulation voltage of up to 1,000VAC or 1,500VDC.  

We also have customers using our standoff insulators in a wide variety of alternative applications, including those where insulation properties are not of prime importance. Standoffs can be used in applications when a distance between two surfaces needs to be maintained. Our design and material choices lead to high mechanical capabilities across the product range. 

Termate have been expertly manufacturing electrically insulating parts for over 60 years, and our range of low voltage standoff insulators exemplifies the quality, design and innovation that are at the heart of our business. Every Termate product is made in the UK, giving our insulators a quality pedigree unlike any other. And just like our other ranges – busbar supports, neutral links, busbar plugs etc, the Termate standoff insulator range has been rigorously tested.  

Termate’s standard range of standoff insulators (lovingly known to us as the Aquila range) includes a wide range of insulators with different heights, footprints and insert sizes, all in a distinctive design. The range is manufactured from flame resistant and halogen free black glass-reinforced polyamide and high-quality brass inserts.  

Unlike porcelain or DMC (dough moulded compound) insulators, our Aquila range of standoff insulators are injection moulded. Because of the differences between compression and injection moulding and the materials used, injection moulding gives a more accurate part. 

As a company, we are taking steps to become as environmentally friendly as possible. By transferring our materials choices to readily recyclable variants, we minimise our contribution to landfill. The runners that we have from the injection moulding process are recycled – currently into horticultural products. 

Having a wide range of sizes in the same design and colour gives our customers the opportunity for a cohesive panel design.  

Our standoff insulators have been subjected to the same rigorous testing as all Termate products, including cantilever, tensile strength and torque. The Aquila range boasts high arc resistance and flammability rating UL94 V-0. They are compliant with the applicable clauses within the international standard for low-voltage switchgear and controlgear assemblies, IEC61439. We can review compliance to other standards upon request. 

The standard range of standoff insulators is available with both metric and imperial (UNC) threads, making them a comprehensive choice for your entire range. 

The metric and imperial (UNC) versions are UL recognised components within the UL categories, Panelboard and Switchboard Accessories – Components and Panelboard and Switchboard Accessories Certified for Canada Component. UL File Number E505645
