Shrink Polymer systems logo - for heatshrink tubing and cable joints


We utilise recognised independent high voltage test laboratories both in the UK and abroad to ensure the products we sell will perform reliably.

Some major switchgear customers also have their own in-house test facilities that we utilise for specific projects.

Testing is normally conducted to BS7888 which incorporates Cenelec, IEC and VDE standards.

We also conduct non electrical testing. Such tests include smoke and toxicity testing for joints used in the London Underground system for which we have approval.
