2.1 SCOPE OF SECTION This Section specifies the material requirements for polyethylene (PE) compound intended for insulation and

for PE insulation taken from the completed cable or where specified, during manufacture. It also facilitates the transition from a prescriptive approach to a performance based specification and therefore allows new combinations of insulation and filling

compounds.

Regarding material selection, the highest performance required of insulation is from installed cable in long service life (>20 years) applications, jointed in outdoor above- ground enclosures that are subject to severe thermal environment (‘more severe

condition’). In such circumstances the entire cable may be designed to survive conditions which only the terminated ends will

experience. Due to the need for ease of re-entry, and standardised work practices, there arc applications that cannot avoid such

conditions, and therefore require the performance of materials and rigour of testing to prove suitability of purpose. However, with lesser service requirements and/or more protective methods of termination, alternative materials and tests for suitability are

presented (‘less severe condition’ and ‘other cables’).
