North Korean cable tray standards

North Korean cable trays are manufactured to meet industrial norms, emphasizing durability, reliability, and long operating life, with types and materials comparable to international standards.

Overview

Cable trays in North Korea are produced by specialized manufacturers such as Cable House, which focus on providing a comprehensive range of products for industrial, commercial, and utility applications . These trays are designed to support electrical cables efficiently while ensuring safety, durability, and long-term performance. The manufacturing process uses graded raw materials and modern technologies to meet prescribed industry norms, ensuring reliable operation over years .

Types and Materials

North Korean cable trays include common types found globally, such as:

• Ladder trays: Ideal for heavy power cables and long horizontal runs, providing strong support and ventilation.
• Perforated trays: Used for power and instrumentation cables, allowing airflow to prevent overheating.
• Solid bottom trays: Protect cables from dust and electromagnetic interference, suitable for control and data cables.
• Basket trays: Common in IT and data centers for routing multiple communication cables.
• Channel trays: Compact and cost-effective, supporting one or two cables in tight installations . Materials used include steel, stainless steel, aluminum, and fiberglass-reinforced plastic (FRP), offering corrosion resistance, strength, and lightweight properties . Aluminum trays are preferred for chemical or coastal environments due to their corrosion resistance, while steel provides good electrical shielding and structural strength.

Compliance and Standards

While North Korea does not publicly publish a unique national standard for cable trays, manufacturers adhere to industry-prescribed norms that align closely with international standards such as IEC 61537, which specifies mechanical strength, corrosion resistance, and electrical continuity for metal cable trays . This ensures that North Korean cable trays are compatible with global practices in terms of safety and performance.
