Lovink Enertech is synonymous with intelligent, innovative and cost-effective solutions, which we design, engineer and test from start to finish. We have extensive and modern test facilities, such as a high voltage and material laboratory and an external test field.
Our tests are conducted in compliance with CENELEC HD 629, IEC 61442 (accessories) and IEC 60455-3-8 (resins). The first of these standards specifies the content and requirements the testing methods must meet; the latter specifies the required values. Besides Lovink Enertech intensifies the testing by conducting the tests at 20 metres head of water (2 bar) pressure, while the standard only stipulates a pressure of 1 metre (0.1 bar). This is because of the specific, heavy characteristics of soil in the Netherlands.
Experience the expertise
In test facilities we can conduct a large number of trials and tests. Not only for our own applications but also for external parties, e.g. customers. Our test engineers are highly educated and have the knowledge and expertise to successfully execute your tests.
Failure investigation
Technically our products have an extremely low failure rate but because of various causes, such as excavation, cable failures or installation errors, failures can occur. Investigating these failures requires a lot of time and expertise. Lovink Enertech can be of help in this. We can analyse on-site and conduct further technical investigation in our test facilities.
