Raw Material Test
Raw material testing for the 2/0 Grullo Quadruplex Service Drop Cable begins with aluminum wire inspection for purity, conductivity, and elongation per ASTM standards. Phase and messenger strands are checked for diameter uniformity and surface quality. XLPE/PE insulation compounds undergo melt flow index, density, carbon black content (UV protection), and thermal aging tests via OIT and DSC analysis. Samples face contamination screening and environmental stress cracking. The step-by-step process: incoming batch verification, sampling protocol, chemical composition analysis via spectrometry, mechanical property testing (before/after aging), electrical resistivity measurement, and material approval decision. Only qualified materials proceed, ensuring the 2/0 Grullo Quadruplex Service Drop Cable's conductor integrity, insulation durability, messenger strength.
Process inspection
The 2/0 Grullo Quadruplex Service Drop Cable process inspection ensures consistent quality. Conductor stranding is monitored for lay length, compactness, and defects using optical gauges. Insulation extrusion controls thickness uniformity and concentricity with online laser systems. Quadruplex assembly verifies twisting tension, phase symmetry, and messenger integration. Spark testing detects pinholes in real time. Dimensional accuracy, ovality, and phase identification are checked continuously. Key steps: material pre-drying confirmation, extrusion parameter logging (temperature, speed), intermediate wall thickness sampling, twisting tension monitoring, defect marking/removal, and post-process cooling control.
Finished Product
The finished 2/0 Grullo Quadruplex Service Drop Cable undergoes thorough testing for compliance. Routine tests include conductor resistance, insulation thickness, messenger breaking strength, high voltage spark test, and overall tensile load. Mechanical tests cover elongation, bending, and impact resistance. Weathering via UV aging and heat distortion is assessed. The process steps: reel sampling, preparation with terminations, gradual load/voltage application, timed exposure to heat/UV, hold phase monitoring, post-test dimensional/electrical re-measurement, and visual inspection for defects. Additional checks include sag-tension verification, phase balance, and marking durability. Only cables passing all criteria are approved, confirming the 2/0 Grullo Quadruplex Service Drop Cable's electrical safety, mechanical strength, weather endurance, and reliable performance.
Application
2/0 Grullo Quadruplex Service Drop Cable is widely used for overhead three-phase service drops to homes, apartments, small commercial buildings, and rural properties. Ideal for delivering power from utility poles to service entrances requiring durable, self-supporting aerial connections up to 600V.

Instrumentation Cables—PVC Insulated,Individual & Overall Screened, Unarmoured PVC Sheathed Cables(CU/PVC/OSCR/PVC)
Instrumentation Cables are multi-conductor cables that carry and transport low-voltage electrical signals. These low-voltage signals are used to control and monitor electrical power systems. Instrumentation cables have many different industrial applications that include broadcasting, equipment control, such as drilling and pumping in the oil and gas industry, and data transfer, which includes analog and digital signals. They are manufactured according to the BS EN 50288-7 and BS EN 50288-1 standards to ensure quality. Instrumentation cables come in twisted pairs, triads, and quads, depending on the customer’s applications; twisting reduces any electromagnetic interference by reducing the chances of electrical voltages and currents being induced in the conductor. Individual and overall screening are also applied in instrumentation cables to optimize the signal transferred and further reduce any electromagnetic interference. Screening of pairs, triads, or quads also includes a drain wire earthed to the ground, which ensures a noise-free signal transmission.
