Daxian Releases DX8427 Tracking and Erosion Tester for IEC60587 and ASTM D2303 Compliance Testing

Dongguan Daxian Automation Equipment Co., Ltd., a high-tech manufacturer of electrical testing equipment established in 2012, presents the DX8427 Tracking and Erosion Tester — a five-station instrument engineered for laboratories that must qualify high-voltage insulators against both IEC 60587-2007 and ASTM D2303.

Tracking and erosion resistance is one of the most decisive performance indicators for silicone rubber, EPDM and epoxy insulators used in transmission lines, switchgear and railway electrification. A single unqualified formulation can lead to surface discharge, carbonised tracking paths and, eventually, flashover in service. The DX8427 was developed to reproduce those aging mechanisms under precisely controlled laboratory conditions, so material scientists and QA engineers can compare formulations and release batches with confidence.

Key Technical Advantages

• Wide, continuously adjustable test voltage: 100 V to 8000 V, allowing both the inclined-plane tracking method and the erosion test to be run on one platform.
• 0.5% dropping accuracy: the contaminant flow system holds a tight tolerance, so the electrolyte delivery rate stays repeatable across long test cycles.
• Five independent test groups: each group is fed by its own peristaltic pump, so samples run in parallel without cross-contamination or interference — five times the throughput of a single-station rig.
• Standard compliance: validated against IEC 60587-2007 and ASTM D2303 test procedures.
• Robust chassis: 1300 L × 700 W × 1800 H (mm), 330 kg, IP57 protection class, supplied for 220 V / 50 Hz operation.

Technical Specifications at a Glance

Why Five Independent Groups Matter

In a conventional single-station tester, an operator can evaluate only one specimen at a time, and a full IEC 60587 evaluation sequence can occupy the bench for days. Because the DX8427 drives each group with a dedicated pump and liquid circuit, five specimens can be tracked simultaneously under identical voltage and flow conditions. That design shortens qualification cycles from weeks to days and, just as importantly, keeps the comparison 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

Manufacturing and Customisation

Daxian operates a production base covering fire testing equipment, environmental chambers and textile testing instruments, and has supplied laboratories in the electrical, construction and consumer-goods sectors since 2012. The company offers OEM, ODM, OBM and software reengineering services, so customers can specify chamber dimensions, data-acquisition software, reporting templates or private-label branding. Every unit is verified against its test protocol before shipment, and a one-year warranty covers the instrument.

Availability

The DX8427 tracking and erosion tester is available for direct order and for OEM/ODM projects. Buyers can request a full technical datasheet, a test-method comparison of IEC 60587 versus ASTM D2303, or a live demonstration before purchase. For laboratories planning a new high-voltage insulation test bench, Daxian's engineering team can recommend the appropriate accessory set — electrode assemblies, filter papers, contaminant solution preparation and calibration fixtures — to build a complete, standards-compliant workstation.
