Paired H1Z2Z2-K conductors keep both DC polarities aligned through repetitive module rows and protected rooftop routes.
Two independent PV singles can separate at turns, cross between rows or require extra clips to keep the route orderly. H1Z2Z2-K Twin keeps both single-core legs joined through the common run, so positive and negative conductors remain physically associated from row to row. This simplifies cable management beneath modules and makes the DC route easier to follow during commissioning, inspection and maintenance.
Large rooftop arrays repeat the same cable path hundreds of times. A twin profile gives installers one paired route to clip, support and dress instead of managing two loose singles independently. The benefit is most visible on repetitive module rows and tray transitions, where consistent routing reduces installation variation and keeps the array underside cleaner and easier to inspect.
The joined construction can be separated at the cable end so each H1Z2Z2-K leg reaches its own connector or terminal while the rest of the route remains paired. This gives installers the handling advantage of a twin cable without changing the underlying single-core PV connection method. It is particularly useful where the route should stay compact but the final positive and negative connection points are physically spaced apart.
Designed for Residential module strings, Commercial rooftop arrays, Cable-tray PV routes and Factory-prepared DC assemblies.

Twin uses two corresponding H1Z2Z2-K single-core legs joined side by side. Conductor OD, insulation, sheath and conductor resistance therefore follow the matching H1Z2Z2-K size. The finished cable dimension is shown as single-leg diameter × paired width; the width and width tolerance are twice the single-leg values. The supplied HORNOUR 2 × 6 mm² datasheet confirms 6.1 ± 0.15 × 12.3 ± 0.3 mm.

Where a certificate, test report or DoP is part of the approval package, we match it to the quoted cable construction and the applicable scope. A document for one version is not treated as approval for another simply because the model name is similar.
Eca is supported by the applicable test report. Dca and Cca are supported by the corresponding CPR certificate and Declaration of Performance. The CPR class, construction and size being supplied must fall within the scope of the supporting documents.
Not automatically. Twin constructions, connectorised extensions and modified constructions such as nylon barrier or steel-wire armour have to be checked against the scope of the applicable documents. For a PV extension lead, CPR evidence for the base cable does not by itself classify the complete connectorised assembly.
