SQ Electricals Ltd manufactures a diverse range of electrical and power products designed to support residential, commercial, industrial, utility, infrastructure, and export markets.
The journey of premium copper products begins with the melting and refining process. SQ Electricals Ltd carefully processes high-purity molten copper under controlled temperatures to ensure exceptional material quality and performance.
This critical stage removes impurities and prepares the copper for casting into high-grade copper rods used in power transmission, electrical wiring, and industrial manufacturing.
Our refining process ensures: High copper purity levels Enhanced electrical efficiency Improved product reliability Reduced impurities and defects International quality compliance Through precision engineering and advanced metallurgical practices, SQ Electricals Ltd transforms molten copper into the foundation of reliable electrical infrastructure.
SQ Electricals Ltd utilizes advanced Upcast Copper Rod Technology to produce high-quality copper rods with exceptional conductivity and consistency. Our automated production line ensures precise control throughout the manufacturing process, delivering premium copper products for electrical cables, conductors, and industrial applications.
With modern equipment and rigorous quality standards, we manufacture copper rods that offer: Excellent electrical conductivity Uniform surface quality Superior mechanical strength High reliability and durability Consistent production standards
Our commitment to advanced manufacturing technology enables us to provide dependable copper solutions for the growing electrical and industrial sectors.
SQ Electricals manufactures high-conductivity copper busbars using advanced continuous extrusion technology, transforming premium-grade copper into precision-engineered busbars with exceptional electrical conductivity, mechanical strength, and dimensional accuracy.
By controlling the entire manufacturing process in-house, the company ensures superior metal purity, uniform grain structure, and consistent product quality, minimizing power losses and enhancing long-term reliability.
Designed to meet international standards, SQ copper busbars are widely used in substations, switchgear, transformers, panel boards, industrial facilities, commercial buildings, and critical power distribution infrastructure.
SQ Electricals utilizes advanced multi-layer co-extrusion technology to manufacture high-performance power cables with XLPE and PVC insulation and sheathing. Precision multi-angle extruders ensure uniform material flow and consistent insulation around copper and aluminum conductors, delivering superior electrical performance and long-term reliability.
The entire extrusion process is continuously monitored by advanced SIKORA X-ray measurement and control systems, which provide real-time, non-contact measurement of insulation eccentricity, wall thickness, concentricity, and diameter. Integrated with automated PLC controls, the system instantly adjusts extrusion parameters to maintain precise dimensional accuracy, minimize material consumption, and eliminate production variations.
This state-of-the-art manufacturing technology enables SQ Electricals to produce low, medium, and high-voltage power cables that consistently comply with international standards including IEC, BS, VDE, and BDS, supporting critical power transmission, distribution, industrial infrastructure, and national electrification projects.
The Lead Extruder manufactured by HFSAB (H. Folke Sandelin AB), Sweden is a critical component of the submarine cable manufacturing process, designed to apply a seamless lead sheath around the insulated cable core.
