Overview

Blaw Knox K8790 is distribution tower series designed by Blaw Knox. Most angle towers bear a strong resemblance to PL16 (with which it is contemporary) making it a “baby PL16” type (the line towers don’t resemble those of PL16).

K8790 appears to have been designed for Preston Corporation; these towers are found in the NWE region and in Kent (SEE).

Note that the towers are yet to be independently verified as a visual match against K8790; the K8790 identification was provided by Electricity North West. The towers in Kent are not necessarily K8790 but are collected here until further information is recovered.

General data

Thorton-Cleveleys variant

Two decommissioned 33 kV lines run between Fleetwood and Thornton-Cleveleys. Most of the line towers have angle tower peaks affording greater earthwire shade. The relationship to Blaw Knox K8790 is not known.

Lines

Discovered lines to date, all 33 kV:

• CT and CM, two short lines (12 and 5 towers respectively) in Middleton, originating near Whitegate substation in Middleton Junction, Greater Manchester.
• RPB: Preston to Blackpool, starting at Ribble GSP substation on an L7 DT (tower RPB 2A) and undergrounded at Staining Wood Farm solar plant outside Blackpool, with tap-off points including Clifton and Wrea Green (part of the route is on parallel wood poles)
• “Medway Grid–Halling”, from Medway Grid substation to a cable sealing end near Luddesdown (over a mile past Halling).

A lone tower used to exist on Darenth Wood Road in Dartford, Kent, but it has since been demolished.

Two lines betwee Fleetwood and Thornton-Cleveleys use line towers with angle tower peaks, listed here for now until further information comes to light.
