Product descriptions from the supplier
Description
Overview
1. The insulation system uses our company's patented "armored shielding" structure and epoxy resin casting process, providing good mechanical strength and strong overload capacity. The product's partial discharge level is less than 3pC, leading the industry. At the same time, the "armored shielding" structure can effectively ensure the safety of equipment and personnel.
2. Applying ANSYS electric field simulation technology to reasonably design the external insulation structure, air gaps, and creep age distances, and optimize the electric field strength of various parts, resulting in a product with small size, light weight, and small space occupation. It is especially suitable for use with lightweight portable equipment and can also be used as a small po wer high voltage power supply.
3. Flame-retardant, fire and explosion-proof, environmentally friendly, low loss, economical operation, and maintenance-free.

Why Regular Transformer Maintenance Matters: 5 Serious Consequences of Neglecting ItI. Allowable TemperatureWhen a transformer is in operation, its windings and iron core generate copper loss and iron loss. These losses are converted into heat energy, causing the temperature of the transformer's iron core and windings to rise. If the temperature exceeds the allowable value for a long time, the insulation will gradually lose its mechanical elasticity and age.The temperature of each part of the transformer during operation is different: the winding temperature is the highest, folRockwell09/12/2025 -

High harmonics? Your transformer may be overheating and aging fast.This report is based on the analysis of one-day power quality monitoring data of your company's distribution system. The data shows that there is significant three-phase current harmonic distortion in the system (with a high total harmonic distortion of current, THDi). In accordance with international standards (IEC/IEEE), harmonic currents at this level have posed substantial risks to the safe, reliable, and economical operation of the power supply transformer, mainly manifested in additional hLeon09/12/2025 -
Ultimate Guide to AC Contactor Abnormal Noise: From Electromagnetic Noise to Mechanical Vibration, Accurate Diagnosis and HandlingIn electrical control systems, AC contactors are among the commonly used electrical components, and they are also a common source of various electrical faults. After long-term use—especially in harsh environments with high levels of dust—AC contactors may sometimes emit squeaking or rattling noises after being pulled in and held. The causes of this phenomenon are analyzed as follows.Squeaking Noise After Pull-In and HoldingA fully functional AC contactor makes no noise when energized and pulledFelix Spark09/11/2025
