Nexans Euromold Connectors : EPDM Rubber Screened Separable Connectors For Medium Voltage Cables
Published 16 Mar 2020
Uploaded by Chris Dodds - Sales & Marketing Manager with Thorne & Derrick International
Nexans Euromold screened separable connectors for terminating medium voltage (MV) polymeric cables onto switchgear and transformer bushings are made from EPDM rubber – EPDM is a terpolymer of ethylene, propylene and a nonconjugated diene.
The resultant hydrocarbon-based elastomer has all the advantages of general purpose rubbers but EPDM rubber performance levels excel in electrical strength and resistance to environmental conditions.
Ozone Corona Resistance
Both EPDM and silicone rubbers used in Nexans Euromold Connectors, Cable Terminations & Joints are resistant to ozone attack – outstanding resistance to corona is due to the ability of EPDM rubber cable connectors, cable joints and cable terminations to withstand ozone and other chemical compounds formed by the discharge as well as its resistance to heat. The excellent fitting due to low hardness of silicone rubber provides excellent corona values.
Resistance To The Environment
Nexans Euromold EPDM rubber screened separable connectors, cable joints and cable terminations have properties comparable with the best speciality elastomers in resistance to weather. Accelerated life and salt spray tests suggested excellent properties which have been proven in practice by more than 35 years experience in widely varied applications in the medium voltage (MV) cable installations. Silicone rubber cable joints and cable terminations have outstanding resistance to weather in aggresive environments (industrial, coastal, desert, offshore).
Resistance To Water
Water has limited effect on Nexan Euromold Screened Separable Connectors manufactured from EPDM rubber – even prolonged immersion in hot water results in minimal loss of tensile strength. Tests also show a very low degree of water absorption – silicone rubbers retain their surface hydrophobicity which is a considerable advantage for outdoor medium voltage cable connecting, jointing and terminating applications.
Resistance To Mechanical Abuse
Nexans Euromold EPDM rubber screened separable connectors have good resistance to compression, cutting, impact, tearing and abrasion over a wide temperature range.
