Pomanique Electric Co., Ltd. 
A coordinated equipment set for lines, feeders and substations.
Transmission and distribution infrastructure depends on dependable interruption, isolation and insulation across a wide operating area. Pomanique supports overhead lines, substations and regional distribution projects with medium-voltage equipment selected around network voltage, fault duty and installation environment.
Key system requirements
Network sectionalizing
Divide long feeders into manageable protection zones to reduce the area affected by a fault.
Safe maintenance
Provide clear isolation points and equipment arrangements suitable for field operating procedures.
Insulation coordination
Match arresters and insulators to lightning exposure, pollution level and system insulation requirements.
Recommended equipment configuration
- Reclosers and load break switchesFeeder automation, fault isolation and operational switching for overhead distribution lines.
- Disconnectors and circuit breakersVisible isolation and high-performance interruption in substations and line terminals.
- Utility fusesBranch, lateral and transformer protection coordinated with upstream protection devices.
- Composite insulators and surge arrestersReliable outdoor insulation and transient protection for exposed infrastructure.
Project support
Provide voltage class, continuous current, interrupting duty, BIL, creepage distance, mechanical loading and site conditions. Pomanique can support equipment selection for a coordinated transmission or distribution package.
