Production methods

RODURFLEX insulators



Patented quality from LAPP Insulators: The production process of the RODURFLEX insulators starts with the extraction of the FRP rod. Cut to the correct length and visually inspected the rods are wrapped seamlessly with a high temperature vulcanised silicone elastomer (HTV silicone). Chemical bonding of the silicone coating to the FRP rod ensures optimum adhesion.

RODURFLEX  – Formed out of high-end-material
Pre manufactured sheds are slid onto the extruded rod and thereby complete the insulator body. This is followed by the high temperature vulcanisation process. This creates a high-strength and permanent bond between the shed and the rod coating. After pressing on the metal fittings through cold forming and after the mechanical routine inspection the joints between GRP rod and fittings are sealed using a special silicone elastomer. Only this elastic material is capable of guaranteeing the absolute tightness of this area and thus safely prevents the ingress of moisture in our RODURFLEX insulator.

RODURFLEX – Customer-specific versions

Using a modular system from FRP rods with different diameters and any length from up to 6 meters, different shed profiles, variable shed number and variable shed distances as well as different fittings the RODURFLEX insulator can be adapted ideally to customer requirements in each case.
