Product Description
LB7-220 type oil-immersed fully-sealed structure Current Transformer

  This product has an oil-immersed fully-sealed structure. It consists
of metal expander, oil conservator, main body and other
accessories. The primary coil is U-shape, the main insulation uses
capacitor type oilpaper, use the high voltage cable paper to wrap
the core of primary coil, and set up several main shields among it.
The secondary coil is set up at the lower part of primary coil; the
whole main body is fixed in the oil tank. There is a bushing at upper
part of oil tank, and an oil conservator is set up on top of bushing, the
primary wire is lead out via the hole of oil conservator, the seriesparallel
switching operation is carried out outside the oil conservator.
Use a stainless steel expander as the oil compensation device to
ensure oil quality. Oil level is indicated by the pointer at the upper window of expander.
A nameplate showing the technical data and a description plate showing the coils arrangement schematic diagram are set
up on the oil tank. There are four holes or lifting blocks on the under-frame for hoisting the product, and an oil-discharge valve
and earthing bolts at bottom of oil tank.
The product can have five or six secondary coils, the secondary measurement coil is made by microcrystalline alloy with
high magnetic conductivity, thus can ensure that the measurement precision reaches up to 0.2 grade or 0.2S grade.
The secondary terminal has limit and double sealing functions. The outlet box is made by stretching wholly; it is elaborate
and practical. The oil tank is carried out surface treatment; it is bright and durable.
Complete transformer is fully sealed. New technology and new materials such as hot galvanizing or stainless steel
standard parts etc are used for outside of the product to prevent from rustless and get long working life.
Reasonable and originative structure as well as advanced technology ensures that the product runs reliably, safely and
durably.
