Rigid lightning protection conductor pipe TTPLAST GROM 32/26, diameter 32/26 mm, length 3 m, model 10750

Rigid lightning protection conductor pipe TTPLAST GROM 32/26, length 3 m, is a hard protective conduit intended for external routing and mechanical protection of lightning down-conductors and grounding cables. The pipe has an outer diameter of 32 mm and an inner diameter of 26 mm, providing sufficient space to accommodate standard lightning conductors while keeping them fixed and shielded from weather and accidental impact. Designed for outdoor installation on building facades or structures, it organizes conductor runs and reduces the risk of physical damage and corrosion exposure.

Advantages

The TTPLAST GROM 32/26 rigid pipe combines dimensional stability with weather-resistant material properties to ensure long-term mechanical protection of lightning conductors. Its 3 m length reduces the number of joints required on façades, and the 32/26 mm diameter offers a balance between cable clearance and compact mounting. The smooth inner surface facilitates cable insertion and the rigid wall supports secure clamps and brackets for external fixing.

Suitable for

• External lightning down-conductor routing on residential, commercial or industrial buildings
• Protecting grounding conductors from mechanical damage and UV exposure
• Facade installations where a rigid, straight conduit is required
• Installations that benefit from fewer joints due to 3 m pipe sections

When it may not be suitable

This rigid conduit is not intended for internal in-wall embedding where flexible or fire-resistant conduit types may be required. It is designed for external use; if a concealed or trunking solution is needed for aesthetic or regulatory reasons, an alternative product should be considered. Also, very large or multiple conductor bundles that require greater internal clearance may exceed the 26 mm internal diameter.

Key specifications

• Outer diameter: 32 mm
• Inner diameter: 26 mm
• Length: 3 m
• Material: rigid weather-resistant conduit (suitable for outdoor use)
• Application: external lightning protection conductor routing and mechanical protection

How to use

Measure and mark the required conduit run along the building exterior, allowing for supports and end terminations. Cut the 3 m sections to length if necessary and use appropriate exterior-rated brackets or clamps to fix the rigid pipe to the façade at recommended spacing. Insert the lightning conductor or grounding cable through the pipe before securing both ends to the earthing system and to the mast or lightning termination points. Ensure joints between sections are properly aligned and sealed where exposure to water or contaminants may occur.

What to consider before purchase

• Verify the conductor size and number of cables to confirm compatibility with a 26 mm internal diameter
• Confirm that the conduit material and mounting method meet local building and lightning protection regulations
• Plan mounting points and bracket type suitable for façade material and wind load conditions

Usage recommendations

For reliable long-term performance, mount the pipe using corrosion-resistant clamps at regular intervals, avoid sharp bends that could pinch conductors, and seal external joints against moisture. Coordinate installation with the overall lightning protection design to maintain continuous electrical continuity and proper grounding.
