Product descriptions from the supplier
Description
The H59 refers to a power transformer where both the high-voltage and low-voltage bushings are vertically installed on the top of the unit. This structural design allows all high- and low-voltage leads to be routed through the top, making it suitable for scenarios with strict lateral space constraints or requiring vertical busbar connections. It is a common type of oil-immersed transformer.
And a high-voltage pluggable bushing-type transformer is one type of H59. It is a transformer designed with pluggable bushings for its high-voltage connections. Compared to conventional transformers. the high-voltage pluggable type offers greater wiring convenience, simplified installation and maintenance, as well as superior sealing and insulation performance.

Distribution Equipment Transformer Testing, Inspection, and Maintenance1.Transformer Maintenance and Inspection Open the low-voltage (LV) circuit breaker of the transformer under maintenance, remove the control power fuse, and hang a “Do Not Close” warning sign on the switch handle. Open the high-voltage (HV) circuit breaker of the transformer under maintenance, close the grounding switch, fully discharge the transformer, lock the HV switchgear, and hang a “Do Not Close” warning sign on the switch handle.

How to Test Insulation Resistance of Distribution TransformersIn practical work, insulation resistance of distribution transformers is generally measured twice: the insulation resistance between thehigh-voltage (HV) windingand thelow-voltage (LV) winding plus the transformer tank, and the insulation resistance between theLV windingand theHV winding plus the transformer tank.If both measurements yield acceptable values, it indicates that the insulation among the HV winding, LV winding, and transformer tank is qualified. If either measurement fails, pairwise12/25/2025 -
Design Principles for Pole-Mounted Distribution TransformersDesign Principles for Pole-Mounted Distribution Transformers(1) Location and Layout PrinciplesPole-mounted transformer platforms should be located near the load center or close to critical loads, following the principle of “small capacity, multiple locations” to facilitate equipment replacement and maintenance.

Risk Identification and Control Measures for Distribution Transformer Replacement Work1.Electric Shock Risk Prevention and ControlAccording to typical design standards for distribution network upgrades, the distance between the transformer’s drop-out fuse and the high-voltage terminal is 1.5 meters. If a crane is used for replacement, it is often impossible to maintain the required minimum safety clearance of 2 meters between the crane boom, lifting gear, slings, wire ropes, and the 10 kV live parts, posing a severe risk of electric shock.Control Measures:Measure 1:De-energize th12/25/2025 -
What Are the Basic Requirements for Outdoor Installation of Distribution Transformers?1. General Requirements for Pole-Mounted Transformer Platforms Location Selection:Pole-mounted transformers should be installed near the load center to minimize power losses and voltage drop in low-voltage distribution lines. Typically, they are placed close to facilities with high electricity demand, while ensuring that the voltage drop at the farthest connected equipment remains within allowable limits. The installation site should allow easy access for maintenance and avoid complex pole struc12/25/2025

Complete Solution for Central Air Conditioning System Retrofit in Mexican Office Buildings (American Standard Distribution Transformer)Ⅰ. Project Background & Pain Point AnalysisThe Mexican office building utilizes a 15HP commercial central air conditioning system originally powered by a single-phase 220V grid. Due to the lack of 380V three-phase driving voltage, the compressor startup current exceeds overload limits (measured at 3.2× rated current), causing refrigeration efficiency to plummet to 40%, accompanied by:Motor winding temperature rise exceeding standards (ΔT > 65°C), reducing insulation lifesp05/19/2025 -
