Dry Type Transformer with Resin Insulation

Description

Low Noise：The core is constructed from low-magnetostriction silicon steel coil material sourced from Baosteel, which serves to reduce magnetic saturation and vibration. The yoke is secured with a through-rod, featuring a 45-degree mitred joint and five-step overlapping, in order to effectively reduce the magnetic flux density. The core column is securely fastened with high-strength PET tape imported from abroad to ensure that the transformer noise level is below 45 decibels.
Low Energy Consumption：The iron core is constructed with 45-degree mitered joints and five-level laminations, offering a no-load loss that is 10% better than the national standard and a load loss that is 5% better than the national standard.
Long Lifespan：The vacuum-plus-positive-pressure pouring process is used, and the partial discharge of the coil is typically less than 5pC. The product features an activated silica powder filler resin with superior thermal conductivity, ensuring a service life of up to 30 years.

Installation Environment	Ensure that transformers with both air-cooled and forced air cooling have adequate ventilation to maintain optimal operating conditions. heat dissipation ventilation device must be added if installed in a basement or other environment with poor ventilation. *Indoor
