Property of EPDM materials
Epdm has perfect performance as one of the main raw materials of cable accessories.
1.Good ability to resist corona and free discharge.
2.High heat resistance;the use temperature for long term is 90℃ and that of the short term is 150℃ .
3.Good mechanical properties
4.Excellent chemical stability and good ability to resist oxophile chemicals,acid and alkali.
Application has proven epdm connectors can effectively resolve the stress concentration of electric field at the port shielding of cable and bear large mechanical stress and play a role in protecting the connecting equipment of cable to guarantee long-term operation.
