Introduction
A: Product Overview
SC(B)10 Dry Type Transformer is three-phase epoxy cast indoor distribution transformer specially developed to convert 10kV, 20kV and 35kV high voltage grid power to 400V low voltage distribution power or secondary 10kV transmission power for global power engineering projects. This SC(B)10 dry type transformer series brings prominent economic and construction benefits widely recognized by contractors; it cuts land occupation and multi-stage substation construction to lower total project investment, eliminates redundant 10kV transformation links to slash long-term operation and maintenance costs, applies high-voltage low-current transmission to reduce cable line loss, and delivers stable power supply for various industrial and municipal power scenarios.
B: Model meaning
C: Producr Features
The SC(B) 10 series 10kV class. 20kV class and 35k cass non-exciting voltage regulating dry type transformers produced by ourcompany are low-loss products, which meet the requirements of national standards GB6450, GB/T10228 and EC726, and have the following characteristics:
- High performance, low loss, and a replacement for the 9 series.
- Selecthigh-quality silicon steel sheet, and greatly reduce the magnetic fux density. reduce the amountof magnetostriction of the siliconsteel sheet during operation, and effectively reduce noise.
- Optimize the structure of the high-voltage coil, improve the distribution of voltage and capacitance between the layers, greatly improvethe produc’s abity to wthstand the atmospheric overvotage and operating overoltage, and also improve the electric field distributionso that the product volume is further reduced.
- The temperature control system and air-cooling device can be configured to automaticaly start the fan cooling device when the load istoo large, which can effectively improve the overload capacity of the equipment.

F: Common Concerns of Overseas Engineering Buyers
Global contractors, factory investors and municipal grid builders usually face 4 core troubles during transformer procurement:
- Unable to match local 10kV/20kV/35kV grid voltage standards, leading to equipment unusable after delivery;
- Unclear loss parameters, resulting in continuous high electricity operating costs in long-term operation;
- Single insulation grade cannot adapt to high-temperature, closed or thunderstorm-prone operating environments;
- Unmatched short-circuit impedance causes damage to supporting high voltage switchgear during short-circuit impact.
