Single-Phase Pad-Mounted Distribution Transformer
Low-profile, highly secure step-down power for modern suburban developments and light commercial connections.
Core Components & Advantages
Tank
Heavy-duty steel enclosure engineered for severe outdoor weather resistance.
Core & Coil Assembly
Precision-wound core and conductors engineered for maximum efficiency.
Bayonet Fuse
Draw-out primary fuse offering quick overcurrent thermal protection.
Drip Shield Assembly
Protective guard preventing fluid drips onto active components during servicing.
Fuse Holder
Heavy-duty internal mounting receptacle accommodating primary protective fuses.
Isolation Link
Internal backup fault interrupter providing high-energy fault clearance.
Link Assembly
Robust internal connection assembly linking key circuit branches.
Pressure Relief Valve
Automatic safety valve venting excess gas and pressure buildup.
Critical Infrastructure Features (7)
Flip-Top Hood & Dead-Front Safety
Lockable, hinged hood secures HV interfaces with 180° crew access while shielding the public.
304 Stainless Steel Base Sill
Corrosion-resistant bottom sill prevents rust from standing water on concrete pads.
Dual-Protection Fuse Coordination
External Bayonet fuse paired with an internal Isolation Link for comprehensive overcurrent protection.
Secondary Set-Screw Terminals
High-conductivity 8-hole connectors deliver low-resistance, vibration-proof terminations.
Loadbreak & Dual-Voltage Switches
External controls for fast line de-energization and quick voltage toggling.
Loop-Feed Topology (H1A/H1B)
Dual 200A high-voltage bushings enable seamless ring-main integration without interrupting downstream power.
Low-Loss Amorphous Core Ribbon
Magnetic amorphous core drastically reduces continuous 24/7 no-load losses.
Additional Benefits
Underground Integration
Designed for ground-level pad placement on underground distribution grids.
Lower Operating Costs
Ultra-high efficiency (>99.25%) reduces lifetime energy losses.
Continuous Reliability
Loop-feed configurations allow line servicing without interrupting downstream power.
Eco-Friendly
Natural ester fluid options minimize environmental impact in the event of leaks.
