Introduction: SPEN has the opportunity to share in the second phase of development of a new design of high operating temperature power cable - SUSCABLE 2. The objective of SUSCABLE 1 was to develop new power cable material technologies with reduced whole-life environmental impact, increased power system efficiency with enhanced sustainability (increased peak-load thermal tolerance) and increased security of supply in urban and environmentally sensitive areas. The outcome of SUSCABLE 1 was new polymer blends with high thermal stability materials with enhanced electrical performance, reduced production costs and improved environmental performance.

Objectives: Design, develop and test a 35kV MV cable that is compatible with 120C continuous operating temperature and 150C conductor emergency rating.

Materials refinement to achieve the MV design, processing and cable production processes.

Cable manufacturing and testing with structured development to generate experience that will be of value in 400kV design, manufacture and testing.
