HDPE solid wall pipes for cable protection HIGH VOLTAGE
ELECTROPIPE – HV

BRIEF DESCRIPTION

High density polyethylene (HDPE) pipes with a solid wall profile, internally and externally smooth, black with red coextruded stripes on the external surface, connectable by butt polyfusion welding (verified according to ISO 13953) in order to be suitable also for the execution of trenchless poses (TOC).

In order to ensure the normal operation of the system with cable temperatures up to 80 ºC, and short-circuit temperatures (not exceeding 5 seconds) up to 160º C, the mechanical characteristics of the pipe meet the requirements of the following standards:

• IEC 62067: Verification of the mechanical characteristics of HDPE conduits for cable insulation for nominal voltages from 150 to 500 kV, before and after thermal aging
• ENA TS 12-24: verification of crushing strain resistance at 50 ºC and 75 ºC

The range of diameters includes:

• all those required by CEI EN 61386, ɸ 25 to 250 mm, in various thicknesses for the different classes of annular rigidity
• all sections up to ɸ 1200 mm, with reference to the SDR classes required by EN 12201-2

MAIN FEATURES & BENEFITS

• IMQ certified standard 61386*
• CE marking*
