Branched solar power cables from Multi-Contact for faster assembly

Connecting solar arrays is an onerous task now made easier with introduction of branched photovoltaic (PV) cables by Multi-Contact. Having the branches already attached to the main cable considerably decreases assembly times, reducing overall costs while also increasing reliability. The continuous main cable also means there are fewer connections, thereby reducing contact resistance.
The high quality cables are produced to order, with customers specifying cable and branch lengths, branch spacings, power ratings etc. They are available with Multi-Contact's popular MC3 and MC4 connector types. Additional flexibility is provided by being able to specify different cable ratings for the main and branch cables.

The cable used is Multi-Contact's chemically cross-linked FLEX-SOL-XL solar cable, which has a usable lifetime of 25 years or more. The complete system offers IP67 environmental protection.

The cables are supplied rolled, bundled and/or sealed in plastic film, depending on their length, and need only to be unpacked and connected at the installation site.

They are also available as endless leads that can be cut to length on site just before installation. This option is suitable for relatively large installations with regularly spaced PV modules.

Cable cross-sections available are 2.5, 4.0 and 6.0 mm2 with a rated voltage of 1000Vdc. The temperature range is -40 degC to +90 degC. TÜV approval is pending.
