Explore the PV Ultra Cable Range

Manufactured in the UK by Doncaster Cables, PV Ultra cable is specifically developed for DC connections within photovoltaic systems. Its multicore design brings multiple conductors together within a single cable, providing a practical alternative to routing separate individual cables between compatible solar system components.

The range includes two-core and four-core configurations in various conductor sizes, alongside steel wire armoured versions for installations requiring additional mechanical protection. These options allow electricians to choose suitable cabling for different solar PV system layouts, including connections between solar panels, DC isolators and inverters.

PV Ultra Cable Sizes Explained

PV Ultra cable is available in several conductor sizes and core configurations to accommodate different photovoltaic system requirements. Selecting the correct cable depends on factors including current demand, cable length, voltage drop, operating temperature and installation conditions.

Popular PV Ultra cable sizes include:

• 4mm² PV Ultra Cable – Available in two-core and four-core configurations, providing a practical option for solar PV circuits where the electrical design permits.

• 6mm² PV Ultra Cable – A popular choice for photovoltaic installations requiring larger conductors, offering flexibility across different cable runs and system arrangements.

• 10mm² PV Ultra Cable – Available within the wider manufacturer range for installations requiring increased conductor capacity or reduced voltage drop over longer distances.

• 2 Core PV Ultra Cable – Combines positive and negative DC conductors within a single cable assembly, simplifying routing between compatible system components.

• 4 Core PV Ultra Cable – Incorporates two pairs of DC conductors, offering a convenient solution for installations requiring multiple DC connections.

For example, the Doncaster PV Ultra 4 Core 6mm² Cable provides a flexible multicore solution for photovoltaic systems.

The appropriate conductor size must always be established through electrical design calculations and the relevant requirements of BS 7671.

Why Customers Choose PV Ultra Cable

PV Ultra combines Doncaster Cables' established British manufacturing expertise with practical features designed specifically for solar PV installations. Its integrated multicore construction helps reduce the complexity of cable routing, making it easier to manage DC connections while achieving a neat and professional installation.

The flexible stranded copper conductors make the cable easier to handle and route through buildings, while its double-insulated construction provides additional electrical protection. The durable SolarTek outer sheath offers resistance to UV exposure, making it suitable for appropriately designed installations in demanding environments.

PV Ultra also features clearly identified conductors and pre-printed LIVE DC safety markings, supporting easier polarity identification and improved awareness during installation and maintenance. Together, these features help electricians work efficiently while maintaining the safety and reliability expected of specialist photovoltaic cabling.

PV Ultra Cable Types and Configurations

PV Ultra is manufactured in several configurations to suit different electrical requirements and installation environments.

PV Ultra 2 Core Cable

Two-core PV Ultra cable incorporates a pair of red and white conductors within a single assembly, providing a convenient solution for positive and negative DC connections. Its construction simplifies cable management while reducing the need to install multiple individual cables along the same route.

PV Ultra 4 Core Cable

Four-core PV Ultra cable contains two pairs of red and white conductors, making it useful for installations requiring multiple DC connections. Available in different conductor sizes, including the PV Ultra 4 Core 4mm² Cable, this configuration can help create an organised installation with fewer separate cable runs.

PV Ultra SWA Cable

PV Ultra SWA incorporates galvanised steel wire armour to provide additional mechanical protection where required by the installation environment. Options such as the PV Ultra 4 Core 6mm² SWA Cable combine specialist DC cable construction with a protective armoured layer.

The appropriate version should always be selected according to the installation route, environmental conditions and relevant electrical requirements.

Quality Standards and Compliance

PV Ultra is manufactured using tinned, flexible copper conductors and double insulation designed to meet the requirements of BS EN 50618 Annex B. Its SolarTek PVC outer sheath provides UV resistance, while the CarbonTek bedding contributes to the cable's protective construction.

The range is designed for photovoltaic DC circuits, with a maximum normal operating temperature of 90°C and a minimum operating temperature of -15°C. Its construction also incorporates clearly identifiable conductor colours and LIVE DC markings to support safe installation practices.

When designing a complete solar PV system, electricians must also select suitable solar inverters, solar isolators and protective equipment. Appropriate solar connectors are essential for compatible terminations, with all components requiring suitable ratings for the intended DC system.

Frequently Asked Questions

What Is PV Ultra Cable?

PV Ultra cable is a specialist multicore DC cable manufactured by Doncaster Cables for photovoltaic installations. It combines multiple insulated conductors within a single cable assembly, helping simplify connections between compatible solar system components.

What Sizes Does PV Ultra Cable Come In?

PV Ultra cable is manufactured in 4mm², 6mm² and 10mm² conductor sizes, with availability depending on the selected product range. Both two-core and four-core configurations are offered, including steel wire armoured versions.

What Is the Difference Between 4mm and 6mm PV Ultra Cable?

The main difference is the conductor cross-sectional area, which affects electrical resistance, current-carrying capacity and voltage drop. A 6mm² conductor generally offers lower resistance than a 4mm² conductor of the same material and length, although the correct size depends on the installation requirements.

Can PV Ultra Cable Be Installed Outdoors?

PV Ultra incorporates a UV-resistant SolarTek outer sheath, making it suitable for appropriately designed outdoor cable routes. The selected cable type, installation method and environmental conditions must be assessed to ensure adequate protection and compliance.

What Is the Difference Between PV Ultra and PV Ultra SWA?

Standard PV Ultra provides double-insulated multicore DC cabling, while PV Ultra SWA incorporates galvanised steel wire armour for additional mechanical protection. SWA versions are useful where the installation environment requires a more robust cable construction.

Is PV Ultra Cable Suitable for Solar Panel Installations?

Yes. PV Ultra is specifically designed for DC connections in photovoltaic systems and can be used for suitable cable runs between compatible solar equipment. The selected configuration must meet the electrical and installation requirements of the system.
