Low voltage accessories are used for building services, industrial machinery, data centres, and smaller-scale distribution networks. They provide mechanical support and protection against environmental influences, helping to maintain safe and efficient operation in commercial and residential environments.

Using high-quality low voltage accessories offers several benefits, including improved electrical and mechanical safety, reduced risk of mechanical damage and lower maintenance requirements over the life of the system. 

For low voltage systems, key priorities are mechanical support, earthing, ingress protection, and maintaining safe clearances. For medium voltage, managing electric field distribution at terminations and joints is critical to prevent partial discharge, premature ageing, and insulation failure. In all cases, appropriate accessory selection and correct terminations underpin long-term system reliability.

Medium voltage accessories are designed for higher-energy applications, including substations, feeders, utility networks, renewable energy installations, and larger industrial facilities that manage higher electrical stresses, fault levels, and insulation requirements.

Meeting the latest standards for low and medium voltage accessories is critical to ensuring safety, reliability, and regulatory compliance. Prysmian designs and tests its low voltage accessories and medium voltage accessories in accordance with relevant international and regional specifications, such as IEC, BS, EN, and other applicable utility or industry standards.

Medium voltage accessories in particular must comply with stringent safety and performance standards covering insulation levels, partial discharge behaviour, short-circuit performance, and environmental resilience. These standards ensure that terminations, joints, and related components can operate safely under higher voltages and fault conditions throughout their service life.
