What are the key challenges in maintaining electrical distribution infrastructure?

Electrical distribution systems are the backbone of modern power networks — ensuring electricity flows reliably from generation facilities to end users. However, harsh environmental conditions, aging infrastructure, corrosion, moisture ingress, and mechanical stress create serious maintenance challenges. These issues can lead to:

  • Equipment degradation
  • Power outages
  • Safety hazards
  • Costly emergency repairs

How can protective coatings and composite repair systems help?

At UNIQUE POLYMER SYSTEMS (UPS), we deliver engineered protective coatings and high-performance composite repair technologies that extend the service life of assets, reduce failures, and minimise maintenance costs across substations, cable networks, transformers, and switchgear systems.

Typical Issues Faced in Electrical Distribution Maintenance

  • Corrosion of transformer tanks, support structures, and switchgear enclosures
  • Water/moisture ingress in cable boxes, joints, and terminations
  • Mechanical damage to substations and housing units
  • Thermal expansion stress due to fluctuating loads and ambient conditions
  • Oil/chemical leaks from aging transformers or fluid storage systems

Left unresolved, these issues can result in system downtime, fire hazards, non-compliance, and high replacement costs.

What protective coating solutions are available for the electrical sector?

Our specialist protective coatings provide long-lasting resistance against corrosion, weathering, moisture, and chemical attack. UPS systems are:

  • Solvent-free
  • Fast-curing
  • Weather- and chemical-resistant

Common Applications Include:

  • Corrosion-resistant coatings for transformer tanks, cable trays, and steel supports
  • Moisture-resistant coatings for junction boxes, electrical cabinets, and terminal housings
  • Chemical-resistant linings for oil containment bunds and fluid storage tanks
  • Elastomeric flexible coatings for vibration-prone areas and expansion joints
  • UV- and weather-resistant systems for outdoor infrastructure

What are composite repair systems and how are they used?

UPS composite repair systems provide in-situ, non-disruptive solutions to damaged or degraded equipment — reducing the need for costly replacements or hot work.

Key Repair Solutions:

  • Metal repair compounds – rebuild corroded transformer tanks and cable boxes
  • Leak sealing kits – stop oil leaks in transformer systems or fittings
  • Structural reinforcement composites – strengthen weakened bases or structural frames
  • Encapsulation systems – protect vulnerable electrical joints from moisture and contaminants

These systems are easy to apply, adhere to multiple substrates, and offer high durability in live operational environments.
