s11/s13 series non-excitation voltage regulating power distribution transformers

1. product introduction
s11 and s13 series products are the most widely used power distribution transformers, mainly used in 10kv distribution network, with capacity range of 30-3150kva and rated voltage level of 10kv. s11 and s13 are energy-saving enterprises, among which s13 series energy-saving transformers are made of high-quality and high-permeability silicon steel sheet. the no-load loss is 27% lower than that of s11, which meets the secondary standard of energy efficiency and has high cost performance.


2. product features
◆ the core material is directly supplied with authentic products, with quality assurance: baowu high-quality cold-rolled oriented silicon steel, unit loss less than or equal to 0.9w/kg; the coil is made of high-quality oxygen-free copper, with copper content ≥ 99.95%
◆ corrugated oil tank, automatic welding, zero leakage rate, surface baking paint, strong anti-corrosion ability
◆ upper and lower positioning of the device body, no core lifting, no maintenance, safe and reliable
