Why Choose Pre-insulated Sleeves That Meet International And Domestic Standards?

Adopting IEC or DIN standard pre insulated sleeve is an essential step in engineering projects. Standardization defines a series of stringent requirements, including dimensional matching of conduits and cable accessories, electrical performance, heat resistance, and environmental resistance. For example, in some high-voltage or shielded cable systems, conduits conforming to DIN EN 50181 can be directly matched with the system's connectors and terminals.

During the product selection phase, the technical team should verify the version of the standard followed by pre insulated junction sleeve. For example, confirm whether insulated joint sleeve specifies the corresponding standard number in IEC/DIN and whether it applies to the expected cable type and rated voltage level. Doing so facilitates smooth subsequent installation work and standard tracking in later maintenance and accountability management.
