Triplex Service Drop Cable
Triplex wire is commonly used for overhead, single phase service and contains three individual wires twisted around each other. The two insulated conductors are called the "hot" legs of the service while the bare (uninsulated) wire is the neutral wire of the service. As mentioned above, this triplexed cable is suited for use as drop cable from a pole mounted transformer to the service entrance of a structure, or as secondary distribution between poles.

Quality Control
Triplex Service Drop Cable
Raw Material Test
NPC has always chosen raw material suppliers who have a good reputation, possess stable supply capabilities and have passed international quality system certifications (such as ISO 9001). And establish a long-term cooperative relationship with it, forming a stable and reliable raw material supply chain.
We will ensure that all raw materials are subject to strict inspection procedures upon entry to the factory, and can only be stored in the warehouse after they have been confirmed to meet the standards.
Process inspection
NPC has strict quality control procedures for each process in the cable production process.
Process documents: Develop detailed process flow and operation instructions to clarify the operating specifications and quality standards of each process.
Equipment calibration: Regularly calibrate key equipment such as wire drawing machines, stranding machines, extruders, and diameter gauges to ensure that the accuracy meets the requirements.
First piece confirmation: Before each batch of production, the first piece is trial-produced to confirm that the process parameters, product dimensions, electrical performance, etc. meet the standards before mass production can be carried out.
Finished Product
Inspectors conduct ex-factory inspections on cables according to relevant standards and corresponding product inspection specifications to ensure that each ex-factory product complies with the process regulations.
Application
Triplex wire is commonly used for overhead, single phase service and contains three individual wires twisted around each other. The two insulated conductors are called the "hot" legs of the service while the bare (uninsulated) wire is the neutral wire of the service. As mentioned above, this triplexed cable is suited for use as drop cable from a pole mounted transformer to the service entrance of a structure, or as secondary distribution between poles.

Quail ACSR Conductor Cable
The ACSR Quail is an Aluminium Conductor Steel Reinforced (ACSR) featuring a galvanized steel wire core (single or stranded) encased in hard-drawn 1350-H19 aluminium layers, meeting ASTM B232 standards. Ideal for overhead transmission and distribution lines, it provides a robust design with Class A or B galvanization, ensuring mechanical strength and electrical efficiency at 75°C conductor temperature.
N2XSY Medium Voltage Power Cable(6/10kV, 12/20kV, 18/30kV)
N2XSY are medium voltage power cables with copper conductors and cross-linked polyethylene (XLPE) insulation, designed according to DIN VDE 0276-620 standards. They are suitable for fixed installations in power distribution networks, industrial plants, and outdoor areas, providing reliable electrical performance and mechanical strength.
556.5 MCM OSPERY ACSR Conductor Cable
The ACSR CAA 556.5 MCM 18/1F OSPREY conductor is a durable and efficient Aluminium Conductor Steel Reinforced (ACSR) cable, engineered to deliver consistent performance in overhead power transmission and distribution systems. With its construction of 18 hard-drawn 1350-H19 aluminium strands wrapped around a single galvanized steel wire, this conductor offers a dependable combination of lightweight conductivity and mechanical strength. Complying with ASTM B232 standards, the OSPREY conductor is ideal for medium- to long-span installations, particularly where increased mechanical support is necessary. The steel core, available with Class A or B galvanization, enhances corrosion resistance while supporting the conductor’s tensile integrity under challenging environmental and load conditions. Its 18/1F construction makes it particularly suited for projects where a balance of performance, durability, and cost-effectiveness is essential. It is widely used by utilities in transmission infrastructure, especially where moderate-to-high current capacity is required without compromising on mechanical reliability.
Instrumentation Cables—XLPE Insulated, Overall Screened, Lead Sheathed, Wire Armoured,PVC Sheathed Cables(CU/XLPE/OSCR/LEAD/SWA/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. Depending on the application, instrumentation cables can be insulated with PVC or XLPE; the cables can be armoured or unarmoured. The sheathing materials can be of PVC, LSZH, or PE. The cables can have additional flame retardant or flame retardant properties, and they can be manufactured with special protections such as lead sheaths, or DRYLAM or AIRBAG technology.
FAQ From Customers
-
What are the advantages of power cables and overhead lines?(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people; (2) The maintenance workload is small and frequent inspections are not required; (3) No need to erect towers; (4) Help improve power factor.
-
Which aspects should be considered when choosing the cross section of a power cable?(1) The long-term allowable working current of the cable; (2) Thermal stability once short circuited; (3) The voltage drop on the line cannot exceed the allowable working range.
-
What are the measures for cable fire prevention?(1) Use flame-retardant cables; (2) Use fireproof cable tray; (3) Use fireproof paint; (4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.; (5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.
-
What should be paid attention to during the transportation and handling of cables?(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat. (2) Before transporting or rolling the cable reel, ensure that the cable reel is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed without damage, the pressure oil tank should be firm, and the pressure indication should meet the requirements.
-
What inspections should be carried out for the acceptance of cable lines?(1) The cable specifications should meet the regulations, the arrangement should be neat, no damage, and the signs should be complete, correct and clear; (2) The fixed bending radius of the cable, the related distance and the wiring of the metal sheath of the single-core power cable should meet the requirements; (3) The cable terminal and the middle head should not leak oil, and the installation should be firm. The oil pressure of the oil-filled cable and the meter setting should meet the requirements; (4) Good grounding; (5) The color of the cable terminal is correct, and the metal parts such as the bracket are completely painted; (6) There should be no debris in the cable trench, tunnel, and bridge, and the cover should be complete.
