Medium Voltage Cable Construction:

Construction will be influenced by the installation parameters, with optional additional component layers providing environmental protections, but it will include the following:

Regulatory Compliance – CPR for MV Cables:

Are regulatory requirements such as CPR compliance applicable to your installation? It may impact the choice of construction and materials used. Some things to consider: 1. Is the cable being used in an internal installation or being terminated inside a building? 2. Geographically where is the installation (is there a minimum CPR class to achieve in a cable)? There are CPR compliant MV cables sheathed in PVC and LSZH materials, holding up to CPR Class Cca, and meeting relevant standards – including holding third-party approvals. Speak to a member of the team and they can help guide you to a cable that meets your requirements.

MV Cable Datasheets

The details below and the technical datasheets provided as PDF downloads are the most commonly specified but variations can be supported. All MV Cable datasheets will provide guidance on application, construction & materials, relevant standards, cable sizes, and electrical characteristics. In the event that further information is required to support specification, or the parameters required do not match any of the listed cable PDF datasheets, please speak to a member of the team who will be able to assist you.

MV Cable Sizes:

Our 10kV, 11kV, 20kV, 22kV, 30kV and 33kV cables are available in the following cross-sectional size ranges (depending on Copper/Aluminium conductors). Larger sizes are often available upon request.

Ravin Cables’ short manufacturing lead times: MV Cable Manufacturer Supply

Once you’ve identified the correct construction and standards, we can supply your MV cables against your project timelines – whether that’s as an urgent requirement coming direct from stock, despatched same-day, or manufactured and delivered against your schedule, via our fleet – including using hiab self-offloading vehicles where needed. Our MV cables are available in specific lengths as well as in extended long lengths to aid installation and to reduce the number of joints. Accompanying cable accessories, with the cable size calibrated to match seamlessly, can also be provided.

Assuring Compliance: Testing Medium Voltage Cables

Given the critical nature of the infrastructure connection created with MV cables, reliability, quality and compliance are vital. To provide the necessary assurances of the manufacturing process to both electrical engineers and their end-user customers, we test all our MV cables in our specialist testing facility under the BSI Kitemark Testing programme. Our MV facility is an extension of The Cable Lab where we undertake tests on cables of rated voltage 3.3/6.6kV and upwards. This includes key tests such as the cable integrity withstand test, also known as VLF testing to determine any failure in the sheathing material. It provides comprehensive quality assurance on British Standard and European/IEC standard MV cables, armoured or unarmoured, as well as industry-specific MV cables such as DNO 11kv and 33kv, and Network Rail trackside power 25/44kV.

Selecting the right MV Cable for your project

It’s essential for the longevity and efficiency of your installation that the MV Cables you specify are closely optimised to match the requirements. There are many options for construction, standards, and the materials used. The format can be single core, three core, or single core triplex. The configurations, materials and properties will be determined by the your installation demands. For support with this, navigating the standards, construction and compliance requirements, contact our technical team by email on technical@elandcables.com or by telephone on +44 (0)20 7241 8500. We can discuss your specific project requirements and our international Medium Voltage cable and accessories solutions.
