Notes on a discussion at the I.E.E. on 'Recent Developments in Polymeric Insulators' (TM-ETR-87)

Nicholson described the British experience gained on polymeric insulators, mainly with reference to Transmission Developments Ltd (TDL) projects. The Connah's-Quay experiment has now been in progress for 10 years; this uses cyclocliphatic resin covered glass-fibre rod cross arms at 132 kV in a marine (River Dee) environment. One insulator (in...
