Single phase pole mounted transformers are the core equipment of single-phase distribution networks. They achieve the conversion from medium voltage to low voltage through a simple structure, providing stable power for small users. It is flexible to install and convenient to maintain, and is an indispensable device in residential power supply and small commercial scenarios. When making a selection, the appropriate model should be matched based on the load size, voltage level and environmental conditions.
Introduction:
Single phase pole mounted transformer is a type of cylindrical step-down transformer that supports installation on utility poles. The high voltage is mainly 6 to 35kv, and the low voltage can be 230v, which can be customized. It is mostly used for power supply in residential areas and small businesses.
It is a key device in single-phase distribution networks, which realizes voltage transformation by utilizing the principle of electromagnetic induction. It features a simple structure, flexible installation and low cost, and is widely used in single-phase power supply scenarios with small electricity loads.
Install the wiring:
Installation location
Single phase pole mounted transformer should be fixed on the electric pole (concrete pole or wooden pole), with a height of no less than 3.5 meters from the ground (to prevent electric shock).
Single-pole suspension or double-pole support structures are usually adopted (suitable for large-capacity systems).
Wiring method
Primary voltage: High voltage connected to the power grid.
Secondary voltage: It can be directly connected to the user’s electricity meter.
Grounding requirements
The neutral point and the casing of the transformer must be reliably grounded (grounding resistance ≤4Ω).
Application scenarios:
Rural power supply: Providing power for scattered residential areas, water pumps or lighting facilities.
Street lamp system: Power distribution for single-phase street lamps in cities or on highways.
Temporary power supply: Short-term electricity demands of construction sites, event venues, etc.
