Marking solution for cabling in PV systems

Professional string marking in large PV installations with marking heat-shrink tubing from BIT:

Reliable labelling solutions for solar parks, ground-mounted PV systems and commercial rooftop installations

Photovoltaic systems are permanently exposed to harsh environmental conditions: intense UV radiation, large temperature fluctuations, moisture, wind loads and mechanical stress continuously act on all system components. A robust solution is therefore required for the safe marking of DC strings, PE conductors and AC-side connections.

Marking heat-shrink tubing from BIT – the robust marking solution for cabling in PV systems

BIT heat-shrink tubing markers provide permanent labelling of cabling (e.g. 4 mm² and 6 mm² solar cables). Thanks to their high resistance to environmental influences, they are ideal for marking in large PV projects such as solar parks or agri-photovoltaic installations.

Optimal integration into the installation process – efficiency meets safety

Whether during the installation of strings, the connection to the module inverter, the routing in the DC main line or near DC combiner boxes (string boxes): the heat-shrink tubing markers ensure clear, permanent identification of all cable runs. Delivery is project-specific, pre-printed according to the string plan and optionally packed by installation zone – ideal for EPC contractors, solar installers and service teams.

Your advantages at a glance:

• ✅ Pre-printed, perforated and packed according to the string plan
• ✅ Suitable for all standard solar cable cross-sections – optimal for 4 mm² and 6 mm² solar cables
• ✅ 3:1 shrink ratio – adapts flexibly to different insulation diameters
• ✅ UL-approved & RoHS-compliant – for maximum fire protection requirements and environmental compatibility

"For me, BIT heat-shrink tubing is the first choice for the structured marking of PV strings in our solar parks. It is printed to our specifications and delivered packed per string. The printing is still clearly legible even after years in the field."

– Andreas Keller, Photovoltaic Project Manager
