Shrink Polymer Systems - Heat shrink cable joints, terminations and cable accessories LV and 11kV to 33kV

Shrink Polymer Systems was established in 1990 to offer a specialised and unique service to the electrical contracting industry, and installer and OEM type businesses worldwide.

The assembly and manufacture of products such as heatshrink tubing for cable terminations, joints, earthing and glanding form the basic product range covering low voltage cables up to 3.3kV and medium voltage cables up to 36kV.

We operate from modern premises in Northamptonshire, UK and operate an independently registered quality system to ISO 9001:2015. Our extensive stockholding and kitting facility for cable type, size and voltage means we can offer complex and non-standard systems on an ex-stock basis.
