Experienced Switchgear Installers and Substation Electricians
Specialist lifting and plant movement is an integral part of many switchgear installation projects, and at Oltec Services we have the trained personnel and procedures in place to manage these activities safely and efficiently. Our switchgear installation teams are experienced with equipment from a wide range of switchgear manufacturers, meaning we can adapt our installation methodology to suit the specific make and model of equipment being installed, whether your project is in Marazion, Cornwall or at a remote site elsewhere in the UK. Following primary equipment installation, our substation electricians take responsibility for the design and installation of cable management systems that are appropriate for the site environment and technical specification, before installing all power, control and fibre cabling.
