2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer

Overview of 2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer

2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer is an enclosed, ground-level electrical distribution transformer commonly used in underground (UG) power systems. It steps down primary high-voltage electricity (e.g., 15kV or 25kV) to a lower secondary voltage (e.g., 120/240V or 480V) for safe distribution to residential neighborhoods, commercial buildings, and industrial parks. Its robust, lockable steel enclosure makes it safe for public areas.

Features of 2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer

Ground-Level Enclosure: A locked, tamper-resistant, weatherproof steel cabinet that protects the internal components and ensures public safety.

Underground Cable Connections: Designed for easy connection to underground primary (high-voltage) and secondary (low-voltage) cables via compartments with built-in bushings.

Compartmentalization: Separate, isolated compartments for high-voltage and low-voltage components, enhancing safety during maintenance.

Ventilation: Designed with louvers or other ventilation systems to allow for proper heat dissipation from the transformer core and coils.

Lifting Lugs: Integrated lifting lugs for easy and safe installation and replacement using a crane or hoist.

Tamper-proof Hardware: Lockable doors with special bolts to prevent unauthorized access.

Fused Switches: Often includes fused disconnect switches for circuit protection and safe isolation.

Pad Foundation: Installed on a concrete pad (“pad-mounted”) to provide a stable, level base.

Specifications of 2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer

This epoxy resin bushing fits three-phase low voltage pad mounted transformers. It handles the electrical connection points. The bushing provides critical insulation between live parts and the transformer tank. Its design ensures safety and long-term reliability.

The key specification is the 2.5KV BIL rating. BIL stands for Basic Impulse Level. This rating means the bushing withstands high voltage surges, like lightning strikes. It protects the transformer windings effectively. The bushing operates continuously at standard low voltage levels. Common system voltages are 600V or 480V. Confirm your exact voltage needs.

Epoxy resin forms the main insulating body. This material is highly durable. It resists cracking and tracking exceptionally well. Epoxy offers strong protection against moisture and chemicals. This prevents electrical leakage over time. The creepage distance is carefully designed. Creepage is the surface path over the insulator. A longer creepage path improves performance in wet or dirty conditions. This reduces the risk of flashover.

The bushing includes metal terminals. These terminals connect the transformer windings to external cables. Terminals are typically tin-plated copper or aluminum. They ensure a solid, low-resistance connection. The bushing features a sturdy flange. This flange mounts securely to the transformer tank. A gasket provides a weatherproof seal. This keeps moisture and contaminants out of the oil.

Installation is straightforward. Follow the manufacturer’s torque specifications for terminal connections. Proper tightening prevents overheating and connection failure. This bushing is designed for pad-mounted enclosures. It withstands typical outdoor environmental stresses. These include UV exposure, temperature swings, and humidity. The material retains its insulating properties reliably. It meets relevant industry standards like IEEE or UL. This ensures compatibility and safety. Regular visual inspection is good practice. Check for cracks, chips, or excessive dirt buildup. A clean, intact bushing is vital for safe transformer operation. It directly impacts the transformer’s lifespan and performance.

Applications of 2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer

This 2.5KV BIL insulator epoxy resin bushing is vital inside three-phase LV pad mounted transformers. These transformers bring power close to where people live and work. You see them in neighborhoods. They power houses and apartment buildings. They sit near shopping centers and offices too. Factories and industrial parks use them. They handle the main power feed for big buildings.

The epoxy resin bushing is key. It insulates the electrical connections. It stops dangerous high voltage from reaching the low voltage side. The 2.5KV BIL rating means it handles big voltage spikes safely. This protects the transformer and the power grid. Epoxy resin is better than old materials like porcelain. It resists water very well. Rain and humidity cause no problems. It stands up to chemicals and pollution in the air. This is important in cities and industrial zones. It handles extreme heat and cold without cracking. Epoxy resin is very strong physically. It doesn’t break easily. Vibration from nearby traffic or machinery is not an issue. This toughness means less maintenance. The transformer stays reliable longer. Power outages happen less often.

This reliability matters everywhere. In residential areas, families need steady power. Businesses cannot afford interruptions. Industrial processes depend on constant electricity. The epoxy bushing makes the transformer suitable for tough spots. It works near coastal areas with salt spray. It functions in dusty desert locations. It performs well in busy urban settings. The design keeps people safe. Workers and the public are protected from electrical hazards. This component ensures the transformer delivers power safely and dependably for many years.

5 FAQs of 2.5KV BIL Insulator Epoxy Resin Bushing Three-Phase LV Pad Mounted Transformer

What does this bushing do?
This epoxy bushing protects the transformer. It safely passes electricity through the metal tank. Without it, electricity could leak or cause a short circuit. It keeps everything inside safe and dry.

Why use epoxy resin?
Epoxy resin protects well. It handles high voltage without breaking down. It resists water, chemicals, and weather damage. It doesn’t crack easily like some older materials. This means the transformer lasts longer outside.

What does 2.5KV BIL mean?
BIL means Basic Impulse Level. 2.5KV BIL shows how much sudden voltage surge it blocks. Think of lightning strikes or power line spikes. This bushing stops surges up to 2500 volts. It prevents damage inside the transformer.

Why three-phase?
Three-phase power is standard for businesses and factories. It delivers more power efficiently. This transformer uses three bushings, one for each phase. This setup handles the heavy loads these places need. It works reliably for industrial equipment.

How is it installed?
The bushings mount directly on the transformer tank. Installers connect the power cables to the bushing terminals. Proper grounding is critical. Following the manufacturer’s instructions exactly prevents mistakes. This ensures safe operation for years.
