KEPCO Ground Transformer

Painting to build environmentally friendly underground facilities in operation of ground transformers and ground switches

Purpose of repair of ground equipment
Maintenance of ground equipment facilities and management of aesthetics and cleanliness from outside
Maintenance of facilities with heavy discoloration and severe film degradation
Prevent the occurrence of civil complaints and safety problems of facilities in advance
Characteristic

SiliUrethane(EPC), which is a functional paint for maintenance paintings, is a product developed by containing functional pigments differently from general paints, and is a paint differentiated in terms of quality and workability. It is advantageous to use not only two kinds of paints such as anticorrosive paints and combination paints but also as one kind of paints, thereby reducing the construction period by more than 50% and economically (construction cost) by more than 35%

Advantages
Prevention of adhesion(Anti-sticker) and stain resistance
Shortening of construction period : Existing combination paint (5 days), SiliUrethane (2 days)
Cost reduction: 35% reduction
Quality assurance effect : Rust film, and combination paint paint show flow, adhesion failure, poor paint compatibility, crack, wrinkle and crack, but the sealant coating is very good.

Functional properties of paints
High temperature resistance : Heat resistance of 150℃~300℃ according to kinds of wires (3, 5, 7).
Good thermal conductivity : Good thermal conductivity to prevent wire surface temperature rise due to poor thermal conductivity.
Corona discharge noise and friction noise reduction functio : Reduction of friction noise due to formation of uniform and slippery coating film and reduction of corona discharge noise caused by local destruction of the atmospheric heat transfer layer due to rainwater.
Good vibration resistance and shrinkage, swelling : Resistant to shrinkage and expansion due to vibration and seasons of electric wire.
Performance characteristics of paints
Rust stabilization function : Stabilizes corrosion oxide (rust) on wire surface to prevent further corrosion.
Good permeability : Porosity Corrosion Oxide and warp-shaped wire with good permeability to fine gaps to increase adhesion force Sealing effect.
Good chemical resistance (acid resistance, alkali resistance) : Acid resistance in harsh conditions, ensuring chemical resistance in seawater particles and air pollution conditions.
Good anti-corrosiveness (weather resistance) : Good corrosion protection.
