1.Service conditions:
1.1 Highest temperature: **0°C;
1.2 Daily average temperature:≤**0°C;
1.3 Lowest temperature:-*0°C.
1.4 Height above sea level:≤***0m (When specially orders for plateau using)
1.5 Relative humidity: <*5% 

2. Main data about products
2.1 AC voltage:≥0.4kV (electric cable)
2.2 Electric network frequency: *0Hz
2.3 Homonymy end: The primary side is L1. The secondary side is K1  
2.4 The model, the data and the outlook sizes see the graph. 

3. Installment
3.1 The unit transformer has no limit of the cable laid or not, the concrete method as follows:
3.1.1 Dismantles the joint sheeting of "K1/" " K2";
3.1.2 Loosening and dismantling the two inner hexagon bolts, then the transformer can be divided into two parts;
3.1.3 The transformer is wrapped on the electric cable, polishes two contact faces, lightly spreads anti-rust oil, twists in the hexagon bolt after corresponding the two parts, the two parts must to be together in order to avoid effecting performance;
3.1.4 Unite the joint sheeting to fix on "K1/" " K2";
3.1.5 The two parts of the unit transformer cannot be exchanged with others of them.

4.Parameter list

 Not:above parameters is for your reference 

5.When order, please supply:
5.1 Product model, inner bore diameter(mm);
5.2 Primary zero sequence current, secondary sequence current (or current ratio)
5.3 Secondary-side loads capacities or loaded impedance;
5.4 Accurate limiting factor, accuracy class (if there is).

(According to the customers demand, our company may design each kind of zero sequence current transformers with different specification and sizes.)
