How To Make Pre-insulated Bushings Compatible With Different Wire Specifications

The pre insulated sleeve's size configuration covers a variety of diameters, from thin signal lines to thicker power lines, to meet the insertion force and contact requirements of different conductor cross-sectional areas. The supplier plans the inner diameter and length of the pre insulated junction sleeve according to electrical industry standards to make it compatible with the industry's standard conductor size.

During assembly, mechanical and electrical connections are completed by inserting the selected wire into the insulated joint sleeve metal contact section. The product design ensures a consistent tolerance range between the wire and the sleeve.

For specific specifications in different application areas, the manufacturer also provides color coding or marking systems to help identify the compatibility range and size class, simplifying on-site identification and installation preparation.
