What maximum pull force can the Vertical Crimper and Tensile Tester exert?
Our crimping and tensile testing machines deliver up to 1,000 kN (100 Tonne) servo-hydraulic force for high-voltage composite insulators up to 1,200 kV ratings.
How does the Batch Weighing & Resin Mixing system prevent air inclusions?
The epoxy/resin system operates under continuous high-vacuum degassing (<5 mbar) with precision gear metering pumps to guarantee zero micro-bubbles in molded insulator sheds.
Are test certificates generated automatically for quality auditing?
Yes — the control system generates NABL-formatted PDF proof load certificates after each test cycle, storing load vs displacement curves for lifetime audit compliance.
Can the Cut-to-Length machine handle thick FRP rod diameters?
Yes — the diamond blade saw cuts solid FRP/fiberglass rods from 10 mm to 120 mm diameter with ±0.1mm length tolerance and zero edge delamination.
How is die wear managed in the Dover/PCA 6-Jaw Vertical Crimper?
Quick-change hardened tool steel jaw inserts can be replaced in under 5 minutes, with digital micrometer radial offset compensation built into the HMI.
What power supply and pneumatics are required for installation?
Standard utility requirements are 415V AC 3-Phase 50 Hz electrical power and 6.0 Bar clean dry compressed air connection.
