Used for withstand voltage testing of 35-500kV series-excited voltage transformers, and also for induced withstand voltage testing of motor and medium/small transformer windings, to assess the insulation strength and withstand voltage level of induction coil type electrical products between turns, sections, and layers. It consists of a three-phase five-column transformer, a matching control box, and reactors. The appearance comes in two types: split type and integral push type.
Input voltage: Three-phase 380V Output frequency: 50Hz
Output voltage: Single-phase 0-300V/0-500V (continuously adjustable)
Output frequency: 150Hz Rated capacity: 5-50kVA
1, Product Introduction
The paper bursting strength tester is a new generation of paper testing instrument developed and produced by our factory. It adopts a microcontroller-based measurement and control method, thereby achieving full digitization and computerization of detection, control, and data processing. All technical parameters and performance indicators comply with the standards and requirements of ISO2758 "Determination of Bursting Strength of Paper", QB/T "Bursting Strength of Paper and Board", and GB454 "Method for Determination of Bursting Strength of Paper".
The instrument is easy to operate, reliable in performance, and advanced in technology. It is an indispensable ideal equipment for scientific research units, paper manufacturers, packaging industry, and quality inspection departments.
