PRE Ειδικής βαρέως τύπου συνδεόμενη μονωτική ράβδος
STANDARD(S) : EN 50508 / IEC 60855-1
USE : Earthing on high and very high voltage lines and substations,
All work involving high mechanical loads.
SPECIFICATIONS :
• Fibreglass composite tube, Ø 39 mm, polyurethane foam-filled, compliant with IEC 60855 (series tested against penetration of humidity).
• Longitudinal dielectric strength 100 kV/30 cm guaranteed in humid atmosphere.
• Screw connectors ref. S46, light alloy with brake and protective sleeve.
• Elastomer hand guard marks the gripping zone.
• Ribbed non-slip shaft. Lgth. and references to order: see table.
Composition:
The PRE stick made up of several sections always has:
- a basic PFE section
- one or more PSE upper sections
- an S46 end adapter suited to the clamp to be handled (see PRE stick adapter connection).
Fixed end fitting :
Ring (AN) and hexagon (HE) fittings can be permanently mounted on the end section: please specify when ordering.
