Product description

LB7-220 (W1, W2, W3, GY, GYW2) current transformer

 

 

Implementing standards
 
The product performance conforms to the national standard GB1208 "current transformer".
 
 
 
Product structure and performance characteristics
 
This type of mutual inductor is a single-phase and capacitive insulation structure. The transformer is composed of body, porcelain sleeve, metal expander, oil tank, etc. The body of the transformer consists of primary winding and six secondary windings. The primary winding is U-shaped. The main insulation is capacitive insulation. The insulation performance of the transformer is stable and reliable through the optimized design of the main insulation and advanced vacuum drying technology. The primary winding is divided into two groups and four outlets are drawn out through the upper side wall of the porcelain sleeve, which can be conveniently connected in series and parallel outside the product to change the current than that of high quality cold-rolled silicon steel sheet (or ultrafine crystal alloy) with high metering accuracy and high accuracy limit coefficient.
 
BT-220 current transformer is a kind of current transformer with transient protection characteristics. It not only meets the requirements of steady-state protection, but also meets the requirements of rapid relay protection and automatic reclosure.
 
 
 
Instructions for ordering
 
When placing an order, please indicate the product type, rated current ratio, number and order combination of secondary windings, whether secondary windings have taps, secondary load and pollution level of external insulation.
 
If the product is used in plateau area, please indicate altitude.
 
The primary wiring board is generally installed horizontally, and can be changed to a vertical installation structure if the user requests.
 
Please refer to the technical department of our company for special requirements.
