Transformer On-Load Tap-Changer Tester

We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.

At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.

The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%


From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:

Waste code: 10 02 10

The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.

Introduction

3 phase transformer on-load tap changer testeris mainly used to test three-phase transient time, transition waveform, transition resistance, synchronization state, etc. The transformer on-load switch tester is a comprehensive transformer on-load switch measurement and tester, which is used to measure and analyze the electrical performance indicators of power transformers and special transformers on-load tap-changers. The transformer on-load switch tester can automatically capture and display the transition resistance during the transition process. There is also a process of time jumping.

Weight: 75Kg

Allow long-term work on the rated current

Allowable overload 1.5 times,30 minutes of continuous work.



Feature

This PSLLQ is make up of input Winding(220V), output winding below 100A and CXRZ.

Output current indicated on the nameplate is defined the rated current that through winding allow to pass.When CX many circles, the rated current its permitted to pass through will inversely decline.

The value which ouput capcity divided by product of output current and each circle voltage was the biggest circle number allowing.



The current booster is designed to provide the primary current power supply for the current transformer when verifying the current transformer or as other 50HZ single-phase power equipment. The current booster for transformer verification is suitable for power departments such as power testing, power measurement, and power maintenance. The current booster is developed and produced according to the industry standard of transformer error testing, and is used as a current transformer to verify the primary current of the current transformer. The output current can be customized according to customer requirements. The lifter is equipped with casters for easy on-site movement.

Tester screw Driver with Neon Bulb, 125mm.

Bath Material is the electrolyte used in the Hall-Haroult process to produce primary aluminium. It's also known as Secondary Cryolite, Crushed Bath, Bath Cryolite, Pure Bath, Bath and tapped Bath Material.

During the aluminium smelting process, surplus Bath Material can be generated because of high Sodium (Na) content in the alumina. This surplus is tapped in a liquid form and then crushed to be reused to start up new pots or to compensate for electrolyte losses.

Bath Material can also be used in aluminium scrap recycling as well as in a number of other processes such as in the manufacture of glass, enamel, ceramics and more.

Gremlog Offers Cryolite in the following sizes : 0-5 mm; 5-20 mm; 20-40 mm ; 0-40 mm

Bath Material, recognized as Secondary Cryolite, Crushed Bath, Bath Cryolite, Pure Bath, Bath, and tapped Bath Material, plays a pivotal role as the electrolyte in the Hall-Haroult process for primary aluminum production.
At Gremlog we offer high-quality Bath Material, allowing for efficient aluminum smelting operations. In the aluminum smelting process, any surplus Bath Material generated due to the high sodium (Na) content in alumina is expertly tapped in liquid form. Subsequently, we crush and recycle this surplus to kickstart new pots and compensate for electrolyte losses.

Our Bath Material goes beyond primary aluminum production, finding applications in aluminum scrap recycling and various industrial processes. Whether you're involved in glass, enamel, ceramics manufacturing, or other industries, our Bath Material proves to be a versatile and valuable resource.
