IEC60587 ASTM D2303 Inclined Plane Tracking Erosion Tester 8000V Five Station Apparatus for Composite Insulators

IEC60587 & ASTM D2303 Inclined Plane Tracking and Erosion Test Apparatus

The DX8427 inclined plane tracking and erosion test apparatus evaluates how high-voltage insulation materials resist surface tracking and erosion under combined electrical stress and controlled liquid contamination. It is built for laboratories qualifying silicone rubber, EPDM and epoxy insulators used on transmission lines, switchgear and railway electrification.

Test Principle

A contaminated liquid is dripped at a controlled rate onto the inclined specimen surface while test voltage is applied between the top and bottom electrodes. Carbonised tracking paths, erosion depth and time to failure are recorded, allowing direct comparison between material formulations and batch release decisions.

Key Features

• 100V to 8000V continuously adjustable output — covers both the inclined plane tracking method and the erosion test on a single platform.
• 0.5% dropping accuracy — tight electrolyte flow tolerance keeps long test cycles repeatable.
• Five independent test groups — each group is driven by its own pump, so five specimens run in parallel without cross-contamination or interference, shortening qualification from weeks to days.
• Standards compliance — procedures validated against IEC 60587-2007 and ASTM D2303.
• Industrial chassis — 1300 x 700 x 1800 mm, 330 kg, IP57 protection class, 220V 50Hz supply.

Technical Specifications

Why Five Stations Matter

A single-station rig occupies the bench for days per full evaluation sequence. Because the DX8427 drives each of its five groups with a dedicated pump and liquid circuit, five specimens are tracked simultaneously under identical voltage and flow conditions. Comparisons stay fair: every sample sees the same contaminant flow, so differences in erosion depth can be attributed to the material rather than the apparatus.

Applications

• Qualification of silicone rubber and EPDM composite insulators
• Incoming inspection of epoxy bushings and instrument transformers
• R&D benchmarking of anti-tracking additives and filler systems
• Third-party laboratory and university high-voltage research
