In high-voltage substations, insulator contamination and pollution flashovers present persistent challenges to electrical reliability. These issues threaten operational stability, particularly in industrial settings. Novacim Cement Factory in Morocco addressed these risks by implementing CharCoat IC Insulator Coating, an innovative RTV silicone elastomer engineered for pollution flashover prevention and high-voltage substation protection.
This case study explores how CharCoat IC enhanced electrical reliability at Novacim’s 225kV substations, delivering robust performance in Morocco’s harsh industrial environment.
Project Overview: Novacim Cement Factory and High-Voltage Substation Protection in Morocco
Situated in Ouled Ghanem, El Jadida, Novacim Cement Factory is a cutting-edge facility under Société Générale des Travaux du Maroc (SGTM). With a capacity of 1.4 million tons per annum (MTPA), it meets the cement industry’s growing demands in Morocco’s Central Economic Region.
This Morocco industrial substation powers a plant that employed over 1,000 workers during construction and now sustains 400 permanent staff. Ensuring electrical reliability through high-voltage substation protection is critical to its success.
Project Challenges: Pollution Flashovers in Morocco Industrial Substations
Operating a 225 KV substation in Morocco’s dusty, industrial conditions introduces significant obstacles. Dust, moisture, and pollution buildup on insulators heighten the risk of pollution flashovers, degrade insulator lifespan, and increase maintenance costs.
Without effective insulator coating, electrical reliability suffers, leading to downtime and productivity losses in the cement industry. Novacim required a solution for pollution flashover prevention to safeguard its Morocco industrial substations.
The CharCoat IC Solution: Advanced Insulator Coating for Pollution Flashover Prevention
Novacim chose CharCoat IC Insulator Coating for its proven efficacy in high-voltage substation protection. This RTV silicone elastomer offers key benefits for electrical reliability:
- Superior pollution flashover prevention by blocking moisture accumulation on insulators.
- Enhanced electrical performance through reduced leakage currents and dry band arcing.
- Cost-effective hydrophobic coating that minimizes maintenance demands.
- Long-term durability for Morocco industrial substations in extreme conditions.
Developed by Mace Technologies and the University of the Witwatersrand Electric Power Research Group, CharCoat IC leverages advanced RTV silicone elastomer technology. Its hydrophobic coating properties prevent conductive layers from forming, making it an ideal choice for cement industry electrical safety and high-voltage substation protection.
Application Process: Implementing CharCoat IC for Electrical Reliability
The application of CharCoat IC Insulator Coating at Novacim’s 225kV substation was executed by Egefen, a specialist in passive fire protection and insulation coating solutions. Since 2020, Egefen has distributed CharCoat products, completing high-voltage substation protection projects across Turkey, Morocco, and Iraq.
Application Steps for Insulator Coating:
- Surface Preparation: Insulators were cleaned and degreased to remove contaminants, ensuring optimal adhesion.
- Coating Application: CharCoat IC, an RTV silicone elastomer, was sprayed uniformly across insulator surfaces.
- Curing Process: The hydrophobic coating cures to form a durable, protective layer.
- Quality Inspection: Coverage was verified to meet standards for pollution flashover prevention and electrical reliability.
This precise process guaranteed long-lasting high-voltage substation protection for Novacim’s Morocco industrial substations.
Results and Benefits: Proven Outcomes of CharCoat IC Insulator Coating
The deployment of CharCoat IC delivered transformative results for cement industry electrical safety at Novacim:
- Effective Pollution Flashover Prevention: Electrical failures due to contamination dropped significantly.
- Reduced Maintenance Costs: The hydrophobic coating minimized insulator cleaning frequency.
- Enhanced Electrical Reliability: Morocco industrial substations maintained consistent performance in dusty conditions.
- Long-Term Value: The RTV silicone elastomer extended insulator lifespan, cutting downtime and replacement expenses.
Before applying CharCoat IC, Novacim faced elevated risks of pollution flashovers and high maintenance burdens. Post-application, the insulator coating ensured operational efficiency and electrical reliability, reinforcing its value for high-voltage substation protection.
Setting a Benchmark for Cement Industry Electrical Safety
By adopting CharCoat IC Insulator Coating, Novacim Cement Factory has established a new standard for high-voltage substation protection in the cement industry. This project demonstrates the critical role of RTV silicone elastomer technology in pollution flashover prevention, delivering electrical reliability in Morocco industrial substations.
CharCoat continues to lead in insulator coating solutions, offering field-tested hydrophobic coatings that meet global standards for cement industry electrical safety.
