“Great involvement of both commerce and product development”

Dutch utility Cogas is responsible for the installation and maintenance of the infrastructure for gas and electricity in the east of the Netherlands.

Gerard Geist, who has been working at Cogas since 1987 – these days as Senior Asset Management Consultant – is very happy with the cooperation. Cogas has been a customer of Lovink Enertech since its incorporation, and the cable joints of Lovink Enertech are used in both the low and medium voltage segment.

One technology

“A few years ago a different technology was used for XLPE on XLPE connections, but now we have completely changed to the LoviSil® technology, for both transition and connection applications.” The greatest advantage, according to Gerard Geist, is that jointers are working with one universal joint and do not have to make a switch when a different type of joint must be installed. “It also makes a difference in stock costs: after all, we only have to keep one type of cable joint in stock”, Gerard Geist says.

Crossbonding joint

In the middle of 2011, the currents in the earth screens were measured. They increased to above 60A, with even some peaks at 100A. This caused Cogas to think about a ‘crossbonding’ application. Gerard Geist explains: “Naturally, Cogas wanted a solution to be found within the present LoviSil® concept, and that was done very successfully.” Recent measurements indicated that the currents over the earth screen have been reduced to 5A. The diagram shows the measurements during a day of the conductor's and earth screen's current load. To conclude, he remarked that the cooperation with Lovink was also successful due to the good contacts: “It is great that the lines are short and that there is also direct contact with the technical developers.”

Erwin Kolman, Operational Manager, is also closely involved with the implementation of the crossbonding joint. “Although the joint was adapted here and there upon our request, there was great faith in the cooperation from the start. After the development, our jointers have been extensively supervised during the installation.” Cogas does not only focus on the quality of the materials, but also on the quality of the people. “You can see this in how involved and solution driven Lovink Enertech employees are. If there is a problem, they are on site very quickly.”, Erwin Kolman says.
