Objectives The objectives of the project are as follows: Design, develop and test a MV polypropylene (PP) blend cable, preferably 35kV, utilising existing cable accessory technologies that are compatible (or readily made compatible) with up to 150°C conductor emergency rating and 120°C continuous operating temperature. Refine the PP blend materials to achieve the MV cable design, processing and cable production processes. The development efforts will also be used to specify material enhancements for EHV cable applications up to 400kV. Undertake cable manufacturing and testing with structured development to generate experience that will be of value in 400kV design, manufacture and testing. Undertake MV cable deployment and operational studies to define the best operating mode and value proposition for Network operators and other MV cable users including economics of deployment with incorporation of risk factors and environmental benefits assessment. Review material thermal properties, cable thermal performance and cable ratings to meet current international standards and develop an action plan to address any identified performance gaps. The project success criteria is the realisation of the following key project activities: Determination of suitable MV cable design Determination of MV cable rating data including deployment and operational studies Deriving optimum PP blend composition and tolerance Identifying preferred semiconductor screen material Identifying preferred cable jacket (sheath) material Testing MV cable Define the HV / EHV cable development programme Determine whole life cable costs and environmental performance Finalising MV cable design and production process
Abstract First generation PVC insulation restricted power cable ratings to 60 - 70°C, subsequent cross linking (XLPE) to prevent the plastic melting offered a continuous rating of 90°C. Recyclable polymer blend materials and process conditions have been developed that avoid the crosslinking and consequently require much lower energy use in manufacturing when compared to that of XLPE cables. The new cable technology also offers the ability to recycle all of the materials at end of life. The new thermoplastics under consideration offer the prospect of an enhanced operating range of 120°C to 150°C. This increased operating head room will lead to improved cable performance. The objective of the SUSCABLE 1 project was to develop new power cable material technologies with reduced manufacturing 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. The SUSCABLE 2 project aims to deliver a 35kV cable based on the new materials and also put in place the materials specification for a 400kV cable.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
