SGB10 series the encapsulation H level dry type transformer adopt (Germany) MORA dry type transformer special technology, make products fully meet the fire waterproof and meet the requirements of environment protection. It is the ideal product distribution system, widely used in the subway, ships, mining, chemical, electric power enterprise and staff of dense buildings, etc. Various kinds of fire safety have special requirements occasion．
Description
Performance characteristics
1. Heat condition is good. hot long life, strong ability of self-learning, over load in over load, IP45 120％ long-term conditions witnout forced air cooling, can long-term full load operation．
2. High security and flame retardant performance °C high temperature, at 800 when combustion without smoke long production.
3. Strong resistance to strike capability in-50 °C (can immediately add full load).
4. 100％ waterproof sealing, excellent hydrophobic, moistureproof sex.
5. Unique coil structure and strong field calculation, make products produced almost no partial discharge.
6. Low loss, remarkable energy saving, and has developed SC9 series dry type transformer 10％ lower than average no-load loss, load loss by 5 per cent.
7. After life cycle can easily will insulating materials and copper separation recycling, not pollute the environment.
Structure characteristics
1. The unique porcelain insulation structure, adopt MORA company insulation and high frequency ceramic cylinder cushion block, never deformation．
2. High and Iow coi| NOMEX insulating materials with first, and approved by VlP vacuum pressure equipment repeatedly dipping special formula, and many insulation class H, external use high strength after roasting insulation material, and high temperature curing sealed. High-pressure coil adopts high mechanical strength, thermal conditions good continuous type structure.
3. Core impored superior high performance magnetic eduction line of outfit and become, stepping type 45° full inclined structure, winding and core using elastic fixtures, make transformer has low no-load loss and noise. After the special craft processing core surface. By pull iron screw moderate clamping, up, or down clip pieces from pull motherboard connections with base, winding and for one, the winding through fixed eIastic cushion block fixed, buffer structure can reduce the vibration intensity and reduce windings noises.
4. Lead outlet terminals fixed in winding, points joints in winding upper DiYaXian terminals for board type central,conductive row, and cold-pressing welding.
FAQs
Our recommendation is that you buy a purpose-built step-up transformer instead of reverse feeding when possible.

The DGA has long been the most reliable and accurate method for determining the internal health of oil-filled transformers. The analysis requires drawing an oil sample from the unit, extracting the gasses from the sample, and analyzing the gasses through gas chromatography. The results of the chromatography tell the lab about different problems that may be arising inside the transformer. Some modern transformers have gauges on them that read levels of dissolved gasses in the oil in real time. But usually, the oil must be drawn and sent to a lab.
If you are unsure if an autotransformer is compatible with a particular piece of equipment, we recommend contacting the equipment manufacturer. However, as a general rule, this issue goes beyond the scope of an equipment manufacturers’ specifications since it is largely dependent on the existing electrical system configuration, where the equipment is installed, and local code requirements.
One hard and fast rule around autotransformer use: If the machine requires a neutral, and your system does not have one, an isolation transformer is required to create that neutral. Autotransformers do not create their own neutrals.
If your primary concern is lead time, repair is almost always quicker than buying a new unit—and this is especially true given the current supply chain crisis.
However, replacing the damaged unit with a reconditioned one can sometimes be just as fast or faster than repairing or replacing with a brand new unit. If an available reconditioned unit matches the dimensions of the unit in need of repair, you can sell the failing one and replace it with the reconditioned one.
Maddox has thousands of reconditioned, ready-to-ship transformers in stock for most common voltage configurations. These are typically available with a warranty comparable or identical to the warranties of newly manufactured units.
