GF1061PT is the first portable device (4.8 kg) which offers highly accurate voltage transformer tests. This allows to use GF1061PT not only for electrical performance checks, but also for class verification and calibration. It performs quick tests of all kinds of inductive voltage transformers (VTs or PTs) and capacitive voltage transformers (CVTs) for both protection and metering purposes. Its lightweight design makes it ideal for on-site tests and calibration tasks in power system grids.
GF1061R portable instrument transformer turns ratio test set is mainly used for field or lab testing of current transformers and voltage transformers, it can fully automatic test CT and PT turns ratio. Adopt 7 inch touch TFT LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data. Test quickly, operation simply

Electrical laminated wood is mainly used for transformers; it is also the insulation material and support material of mutual inductor. Besides, it can be used to make winding clamping plate, iron core plate, trapezoidal plate and clamping device. And it has many advantages, such as proper specific weight, high mechanical strength, good compatibility with transformer oil and easy machining. In addition, its dielectric constant is close to that of transformer oil and the insulation coordination between them is proper. It can be used in transformer oil under 105â?? for a long time.
Electrical laminated wood sheet is widely used in manufacturing some devices for oil-filled transformer, such as upper and lower pressure plate, lead bracket and iron yoke cushion block. And it is used to make clamping device in mutual inductor. It can replace steel plate, insulation paper board, epoxy paper board and epoxy fiberglass board, which can lower the weight of the transformer and the cost of materials.
Rated Capacity: 30~2500KVA
