Tension transformers the inductive gas - filled ZNOG - 110,220 series (further "tension transformer") general purpose intended for signal transmission of measuring information to measuring devices and devices of protection, the alarm system and managements in the opened and closed distributing devices of alternating current of the frequency of 50 Hz on rated voltage 110 / √ 3 kV.
The transformer of tension is intended for operation in macroclimatic areas with a temperate and frigid climate (climatic modification of U1, UHL1 in accordance with GOST 15150 - 69), at the same time:
Mechanical loading from wind speed up to 40 m/s and from a tension of wires in the vertical direction to the plane of conclusions – 1000 N (100 kgfs) and the horizontal direction in the plane of conclusions – 1000 N (100 kgfs).
Example of record of a symbol of the transformer of tension grounded single - phase, electromagnetic, gas - filled with a porcelain tire, with secondary windings of classes of accuracy 0,2 (one) for the account, 0,5 or 0,2 (one) for measurement and 3P (one) for protection; a class of voltage of 110 kV, category II * depending on length of a way of leakage of external isolation, climatic modification At, or UHL of category of placement 1 in accordance with GOST 15150:
