The JLDZ8-10 outdoor winding injection type combination transformer adopts an epoxy resin casting fully enclosed structure, which is maintenance free,
Characteristics of all operating conditions. Voltage transformers have overvoltage resistance and are designed with low magnetic flux density. Current transformers have high dynamic and thermal stability. This type of combination transformer FDK4-12/D400-16 electromagnetic AC high-voltage automatic sectionalizer is used in conjunction with it.

Installation, maintenance, and precautions
The installation base plate of this product is welded with channel steel, and the surface is hot-dip galvanized. There are four straight installation holes on the base plate, and users can directly fix the base plate on the metal component. There are two lifting rings on the base plate for easy lifting.
The secondary part of this product is connected to the user equipment control cabinet using an outdoor waterproof aviation plug, making installation very convenient.
The following points should be noted during the use of this product:
① Short circuits are strictly prohibited at the secondary terminals of voltage transformers.
② To avoid the impact of external forces on high-voltage insulators, when the insulation surface is damaged, the insulation capacity and internal abnormalities should be checked in a timely manner.
③ The product should be stored in a dry, non corrosive gas environment.
