Coventry 33 kV
Contents
Overview
Two lines partially enclosing Coventry use a tower type similar to those used by Preston Corporation (Blaw Knox K5257 and K8790). The most distinctive feature of this type is that the 10° towers are of the suspension type. The lines currently operate at 33 kV but the towers appear to have 66 kV clearances.
The towers are without a doubt a Blaw Knox design. The suggested design evolution of this pattern of towers would put the Coventry type in between the Preston Corporation types of Blaw Knox K5257 (suggested to be 1940) and K8790 (1945), making this another wartime type. This remains to be confirmed.
Coventry is also notable for being the location of the L2 DMC tower suite (L2 with extended middle crossarms).

Lines
Only a single route around the outside of Coventry, from the west side to the north side, is known. There are two lines comprising three segments:
- Coventry West substation to Hawkesmill Lane substation (Hawkes End), continuing directly onto
- Hawkesmill Lane substation to Coventry Colliery substation (line terminates here)
- A second line from Coventry Colliery substation to the far side of Ash Green
There is a small amount of PL16 heading towards Coventry Colliery substation.

From historic Street View imagery it can be seen that the D10 type originally used droppers (not brackets) for the suspension insulator sets. In recent years these have been removed and replaced with entirely new suspension brackets, rather than the conventional practice of converting D10 suspension towers to tension insulators.
