High-Quality PVC Insulated Concentric Cable: Meeting Global Standards for Reliable Power Transmission
In the dynamic landscape of power transmission, Concentric cable has emerged as a cornerstone for safe and efficient electricity supply, especially in residential, commercial, and industrial applications. Our factory specializes in manufacturing PVC insulated single-phase concentric cables that adhere to stringent international and regional standards, ensuring consistent performance and long-term reliability for global clients.
Product Overview: PVC Insulated Single-Phase Concentric Cable
Our Concentric cable line is engineered for operation up to 1000 Volts between phases and 600 Volts to earth, making it ideal for low-voltage power distribution networks. Each cable features a central phase conductor insulated with red PVC, paired with a concentric layer of bare copper wires serving as a combined neutral-earth conductor— a design that enhances electrical stability and simplifies installation.
Key Specifications & Standard Sizes
We focus on batch production of high-demand concentric cable sizes, with each variant meeting the requirements of IEC 60502-1 and Kenya Standard KS 04-1022. Our core product range includes:
-
10 sq. mm PVC Insulated Single-Phase Concentric Copper Cable
-
16 sq. mm PVC Insulated Single-Phase Concentric Copper Cable
-
25 sq. mm PVC Insulated Single-Phase Concentric Copper Cable
In addition to standard sizes, we also offer four-way Concentric cable for specialized projects. Contact us now to get factory-direct pricing and customized solutions tailored to your market needs.
Compliance with Global Standards
Quality and compliance are non-negotiable in our manufacturing process. Our Concentric cable strictly follows two key standards to ensure compatibility and safety across different regions:
-
IEC 60502-1: This international standard governs power cables with extruded insulation for rated voltages from 1kV (Um = 1.2kV) up to 30kV (Um = 36kV), covering cables for 1kV and 3kV applications.
-
KS 04-1022: The Kenya Standard Specification for 600/1000V PVC-insulated single-phase concentric cables, ensuring our products meet the specific requirements of the African and other regional markets.
In case of any document conflicts, our internal product specification takes precedence, with all materials and processes aligned to the latest revisions of these standards.
Material & Construction Excellence
Every Concentric cable we produce is built to last, with meticulous attention to material selection and construction details:
1. Phase Conductor
-
Circular stranded annealed copper conductors (Class 2) as per KS 04-1022, ensuring excellent conductivity and flexibility.
-
Left-hand direction of lay for consistent performance and ease of handling during installation.
-
Red PVC insulation compound (compliant with KS 04-1022) applied via extrusion, with mandatory spark testing to eliminate defects.
-
Insulation thickness meets or exceeds Table 1 requirements, with minimum measured values not falling below 10% + 0.1mm of the standard.
2. Concentric Neutral Layer
-
Plain annealed copper wires (KS 04-1022 compliant) forming a concentric neutral conductor, enhancing grounding efficiency and fault current handling.
-
Right-hand direction of lay for optimal structural integrity.
-
Number of wires and resistance values strictly adhere to Table 1 specifications, ensuring electrical performance consistency.
3. Oversheath
-
Extruded black PVC compound (KS 04-1022 standard) providing robust protection against environmental factors, abrasion, and moisture.
-
Spark-tested to guarantee insulation integrity, with minimum thickness deviations limited to 15% + 0.1mm of the specified value.
