An electrical surge diverter/arrester comprises a non-linear resistor arrangement (1) between end caps (2) formed with terminal posts (3) and with one or more electrically insulating reinforcing rods (6) extending through bores in the resistor and a heat-shrink sleeve (4) serving to secure the assembly together, the sleeve (4) compacting the end caps (2) onto the resistor arrangement (1) for ensuring good electrical connection therebetween. A plurality of sheds (5) can be integral with the sleeve (4) or separate therefrom. The heat shrink material may incorporate an anti-creepage tracking agent. The invention avoids the risk of explosive shattering associated with porcelain housing. <IMAGE> |
