Telecommunication Apparatus
I have advised on over 2000 incidents where damage has occurred to electromechanical, co-axial and optic fibre cables operating in the core and access networks of the telecommunication network operators in the UK. The highest value telecommunication claim investigated attracted invoiced costs in excess of £700k.

These investigations related to the following procedures:-

• Installation and repair of damaged underground ducting arrangements.
• Replacement and repair of damaged underground jointing chambers.
• Installation of newly constructed ducting arrangements and the associated underground jointing chambers.
• Replacement and repairs associated with cabinets housing Primary Cross Connection Points.
• Repair procedures associated with electromechanical copper and aluminium conductor cables.
• Repair procedures associated with optic fibre cables.
• Repair procedures associated with co-axial cables.

Electricity Distribution Equipment
Chapter House is recognised as one of the leading advisors relating to damage which has occurred to electricity distribution apparatus owned by the Distribution Network Operators in the UK and Southern Ireland. My expertise covers a range of electricity distribution apparatus from low voltage networks to transmission gas and fluid assisted cables operating at voltages up to 275kV. The highest value claim that has been investigated had a potential at risk value in excess of £55 million, which involved potential damage to a 275,000 volt cable.

These investigations relate to cables of the following specifications:-

• Lead alloy reinforced sheath, aluminium sheathed and Mollerhoj fluid (oil) filled transmission cables and their associated hydraulic systems operating at voltages ranging between 20,000 and 275,000 volts.
• Gas assisted aluminium sheathed transmission cables operating at 33,000 volts.
• Solid type lead alloy sheathed cables operating at voltages between 20,000 and 132,000 volts.
• Polymeric cables operating up to 132,000 volts.
• Solid type lead alloy sheathed, aluminium sheathed and polymeric cable operating at voltages ranging between 6,600 and 11,000 volts.
• Low voltage distribution cables and service connections.

Areas of expertise in relation to the electricity distribution apparatus also extends to the following equipment:-

• Cable terminations, switchgear, transformers and ancillary apparatus in electricity substations operating at voltages between 230 and 132,000 volts.
• Overhead line structures and the associated underground cable terminations operating at voltages between 230 and 132,000 volts.
