ZX-HM Insulator Non-soluble Deposit Density Tester: A Technical Overview

For maintenance and engineering professionals in the power transmission and distribution sector, accurately measuring the non-soluble deposit density (NSDD) on insulators is critical for assessing contamination levels and preventing flashovers. The ZX-HM Insulator Non-soluble Deposit Density Tester presents a comprehensive, integrated solution designed for simplicity and precision in this essential testing procedure.

This system integrates all necessary components—an electronic balance, an air blast drying device, a vacuum filtration unit, and accessories—into a coherent workflow, streamlining the entire process from sample collection to final measurement.

Key Features & Technical Advantages

A primary advantage of the ZX-HM system lies in its thoughtful integration and component design:

1.Efficient Vacuum Filtration: The vacuum filtration device is a standout component. It features multiple taps, enabling simultaneous processing of several samples, thereby significantly increasing laboratory throughput. A key design improvement is the use of a water circulation device instead of a traditional oil circulation pump. This substitution enhances user convenience, reduces maintenance needs, and results in a lower failure rate.

2.Advanced Air Blast Drying: The drying apparatus incorporates advanced German technology for its air duct design. This ensures efficient and uniform drying while keeping fan noise to a minimum. It offers precise temperature control with a range from room temperature +10°C to 250°C, a resolution of 1°C, and excellent stability (±1°C fluctuation and uniformity).

3.High-Precision Measurement: At the heart of the system is a digital electronic balance with a precision of 0.1mg and a maximum capacity of 200g. It includes essential functions for technical work such as calibration, self-checking, and multiple weighing modes, ensuring the integrity of the final NSDD calculation.

Comparative Perspective

When compared to traditional setups where balances, drying ovens, and filtration units are often sourced separately and integrated on-site, the ZX-HM offers distinct benefits. Traditional methods can be plagued by compatibility issues, procedural inconsistencies, and higher maintenance demands—especially with older oil-based vacuum pumps. The ZX-HM's all-in-one approach standardizes the testing protocol, reduces potential error sources, and improves operational efficiency. The multi-tap filtration system, in particular, offers a clear productivity advantage over single-filter assemblies commonly found in basic setups.
