PVC Insulated Crimp Terminals are very popular and are often preferred to F-Type Ring Terminals (also known as non or un-insulated crimps) because apart from their insulation properties they also offer extra support for the cable as it enters the crimp terminal and due to the industry standard colour scheme it ensures that the crimp and the wire size are matched. They also form a very neat and aesthetically pleasing crimping solution. The standard red, blue, yellow insulation colour scheme is common amongst all crimp terminal manufacturers however there are slight variations in the wire sizes quoted by them. Generally red insulation is for wire sizes from 0.25mm2 to 1.5mm2, blue from 1.5mm2 to 2.5mm2 and yellow from 4.0mm2 to 6.0mm2. Some manufacturers also offer ranges for smaller wire sizes from 0.2mm2 to 0.5mm2. These are typically in yellow or green insulation. ...For help in choosing the correct crimp tool for your application please see our tooling for insulated crimp terminals section. For those who want to take the strain out of hand crimping we have an excellent range of battery tools for insulated crimp terminals and for high volumes we’d suggest reeled terminals from JST together with their JST AP-F6 Pneumatic Bench Press. For areas exposed to excessive vibration, JST and Cembre offer ranges with an anti-vibration sleeve. Please contact us if you need more information on these products. If you need pre-insulated crimp terminals for wires from 0.25 to 6.0mm2 and they need to withstand higher temperatures than the standard 80oC for PVC insulation then we offer; Nylon Insulated Crimp Terminals (up to 105oC), Polycarbonate Insulated Crimp Terminals (up to 115oC) and Kynar Insulated Crimp Terminals (up to 150oC). Pre-insulated Crimp Terminals are also available for larger wire sizes. Klauke offer a range of Nylon insulated sheet terminals from 10mm2 to 150mm2 in a repeating red, blue, yellow colour scheme. You can find these in the Nylon insulated ring terminal section of our website. For heavier duty work there are also pre-insulated copper tube terminals available for cable sizes from 10mm2 to 150mm2 from both Klauke and Cembre. For details please see either, Klauke insulated tube terminals or the Cembre ANE range. Please note that it is recommended by both manufacturers that these insulated cable lugs are to be indent or oval crimped, not hex’ crimped, as would be standard practice with non-insulated tube terminals.
