Quality Control

Control Cable 0.6/1 kV CVV-SWA to IEC 60502 Standard (2-16 core)

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

For use in duct, tray, and direct burying in the ground. The cable is subject to being immersed in water all the entire line.

Instrumentation Cables CU/PVC/OSCR/PVC are PVC Insulated, Overall Screened, Unarmoured PVC Sheathed Cables. They 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.

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.

(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.

How many projects can cable engineering be divided into?

(1) Construction site transportation: including the loading and unloading, transportation and empty vehicle return journey of engineering materials from the warehouse to the construction site.
(2) Local engineering: including road excavation, tunnel, trench construction, etc.
(3) Laying engineering: including laying, intermediate head production, lift cover plate, buried pipe, school tide, tractor head production, etc.

What tests and inspections should be carried out on power cables before laying?

Before laying, check whether the type, specification and length of the cable meet the requirements and whether there is external force damage. Low-voltage cables use a 1000V megohmmeter to remotely measure the insulation resistance, and the resistance is generally not less than 10MΩ. High-voltage cables use a 2500V megger to measure the resistance. Generally not less than 400MΩ.

What are the factors that determine the long-term allowable current carrying capacity of the cable?

(1) The long-term allowable working temperature of the cable;
(2) The heat dissipation performance of the cable itself;
(3) The condition of the cable installation and the heat dissipation conditions of the surrounding environment.

According to the difference of insulation and protective layer, what are the main types of commonly used low-voltage power cables?
