However, depending on the depth of the underground cable; greater EMF may be experienced on the surface. [4] The electric current in the cable conductor produces a magnetic field, but the closer grouping of underground power cables reduces the resultant external magnetic field, and further magnetic shielding may be provided.
Two 3-core XLPE cables with total capacity of 2x200MVA. 174 km total length including the underground segments. Maximum depth 1000m. Total cost 380 million EUR. It is the longest submarine/underground AC cable interconnection in the world. [6] [7] [8]
Aluminum in power transmission and distribution applications is still the preferred wire material today. [3] In North American residential construction, aluminum wire was used for wiring entire houses for a short time from the 1960s to the mid-1970s during a period of high copper prices.
PVC-sheathed MICC cable. Conductor cross section area is 1.5 mm 2; overall diameter is 7.2 mm. Mineral-insulated cables at a panel board. Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder.

In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ...
