Elpress has long cooperated with demanding manufacturers of wind power and with their subcontractors for cabling. In these contacts, it has become clear that there is a broad spectrum of various requirements that are considered to be relevant to work with in wind applications.
Besides the requirements in electrical characteristics and current-carrying capacity, wind applications can also comprise high standards in terms of corrosion, vibrations and static loads.
Elpress has together with the customers identified the following test standards as being considered relevant for wind applications:
• Electrical properties - IEC61238-1, class A.
• Environmental requirements - DIN V 40 046, part 37.
• Static loads - Swedish Standard SEN 245010 provides relatively high load limits and is therefore useful here.
• Vibration testing - EN 50155 has been used where applicable.
Elpress has extensive experience in the wind power industry and our ambition to provide qualified materials and knowledge for electrical connections, together with a high level of service and product knowledge, means that you get a secure connection.
For crimping of flexible conductors in KRF/KSF joints in demanding applications.
The technology has been developed to meet the needs of manufacturers with high standards on applications in extra demanding environments where the connection, besides electrical properties, are also subjected to e.g. corrosion, vibrations and mechanical strength.
DUAL crimping process
Contact crimping takes place in a two-stage movement, first a hexagonal crimping that provides optimal symmetrical contact with the conductor, which means that no wires are broken or come apart in the edge facing the connector. This is followed by punch crimping, which provides 30% better electrical properties.
