FAQs
Q1:Should a single pole or a double pole be used to install the 100kVA and 150kVA pole mounted transformer?
A: Double pole (H-shaped pole) must be used. Transformers with a capacity of 100kVA and above are installed in a double pole configuration, which consists of a main pole and an auxiliary pole forming the support column. The two poles are clamped with channel steel to form a bearing seat. According to the information, transformers with a capacity of over 100kVA also require the installation of isolation switches.
Q2: What is the distance between the two poles?
A: The distance between the two poles is 2 meters, and the transformer is allowed to tilt no more than 20 millimeters on the pole.
Q3: How to choose between 100kVA and 150kVA?
A: Determine based on actual load:
The load is stable between 70-80kW →100kVA is sufficient;
Load approaching 90kW or potential for growth → 150kVA (need to confirm if there is stock available);
Paired with high-power motors (such as 50kW or above) → It is recommended to directly apply 200kVA.
Q4: What are the horizontal requirements for seat installation?
A: The ratio of the height difference between the two ends of the seat to the horizontal distance (plane slope) should be less than 1/100.
