Note: Above Is Standard Parameter About Our Pole Mount Transformer
Custom Pole Mount Transformer Solutions
Each unit features a cold-rolled grain-oriented (CRGO) silicon steel core optimized to reduce no-load losses by 15-20% compared to industry baseline designs, with copper or aluminum windings available to match project budget and performance requirements
The welded steel tank is nitrogen-purged during assembly and equipped with pressure relief devices, oil level gauges, and durable porcelain or polymer bushings rated for regional lightning impulse levels, with optional completely self-protected configurations integrating primary and secondary circuit breakers plus lightning arresters directly into the tank to eliminate the need for external protection equipment

Pole Mount Transformer Application
Pole mount transformers are widely used in overhead power distribution networks for stepping down high voltage to low usable voltage. Our pole mount transformers are ideal for residential communities, rural power grids, villages and remote countryside electrification. They serve small commercial buildings, street lighting systems, roadside facilities and rural farm power supply. They also support temporary construction sites, mining area branch power supply, rural agricultural irrigation and small industrial workshop power distribution. Suitable for outdoor overhead installation, Sinotech overhead transformers adapt to harsh weather, coastal areas, high temperature and humid regions. Compact and easy to install, they are the preferred choice for urban and rural low-voltage distribution, decentralized load power supply and public utility power projects.
