ABB POLIM-D..PI surge arresters are used for the short-circuit protection of medium voltage and high voltage electrical equipment and cables against overvoltages caused by lightning, atmospheric discharges and switching conditions up to 52kV.

ABB POLIM-D..PI surge arresters are designed for indoor and outdoor use and with metal-oxide (MO) resistors without spark gaps molded in silicone rubber with a touch-proof metal clad design housing and tested according to IEC 60099-4 and is applicable for inner cone systems according to DIN EN 50181 and DIN 47637.

  • IEC 60099-4:2014  – Part 4: Metal-oxide Surge Arresters Without Gaps For a.c. Systems
  • DIN 50181:2011-04 – Plug-in type bushings above 1 kV up to 52 kV and from 250 A to 2,50 kA for equipment other than liquid filled transformers; German version EN 50181:2010
  • DIN 47637:1986-01 – Separable accessories for power cable for bushing with inside cone; Uₘ= 36 kV, inside cone and fastening for the separable connector

ABB POLIM-D..PI surge arresters are available in cone size 2 or 3 and are for use with MV-HV cables, transformers, and metal-clas switchgear – T&D distribute cable joints, terminations and connectors to support the construction of electrical networks, substations and overhead lines for 11kV, 33kV and up to 66kV.

Surge arresters should be installed as close as possible to the medium/high voltage electrical equipment to be protected within the protective distance with sheds pointing downwards – minimum permissible distances between the surge arresters and the earth must be observed.

Earthing Surge Arresters

Installers must observe national regulations and the requirements of the system owner/utility. ABB POLIM-D..PI surge arresters should be connected to the system ground via the shortest path – all contact surfaces should be cleaned and lubricated with acid-free contact grease.

Observe recommended minimum diameters for ABB POLIM-D..PI arresters:

  • Copper Diameter 20mm
  • Aluminium Diameter 40mm

Commissioning MV-HV Medium & High Voltage Surge Arresters

Due to the risk of electric shock only authorised personnel should work on ABB POLIM-D..PI surge arresters and observe BS EN 50110-1:2013 Operation of Electrical Installations – the MV-HV power system should be disconnected from the power supply, de-energised and grounded using portable short-circuit earthing kits for either substation or overhead line applications. If live-working is required and unavoidable around electrical equipment a calculation of arc risk should be sanctioned and appropriate arc flash protection clothing worn.
