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.

(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.
(4) Two-end engineering: including the production and installation of support, suspension bridge and its foundation, the production of terminal heads, the installation of oil pressure and signal devices, and the electrical performance testing of various types.
(5) Stopping works: including the production of oil-filled cable stop heads, the installation of fuel supply tanks, automatic drainage and signal devices, etc.
(6) Grounding engineering: including installation of insulation joints, transposition boxes, protectors, and grounding boxes.

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?

(1) Oil-impregnated paper insulated lead-clad (or aluminum-clad) power cable;
(2) Non-drip oil-impregnated paper insulated power cable;
(3) PVC insulated and sheathed power cable;
(4) Cross-linked PVC insulated and PE sheathed power cable;
(5) Cross-linked PVC insulated and sheathed power cable;
(6) Rubber insulated power cables.

What are the requirements for the fire blocking of cable holes?

For larger cable penetration holes, such as the cable penetration floor, etc., when using fireproof blocking materials to block, according to the actual situation, first coat four to six layers of fireproof paint on the cable surface, the length is about 1.5m below the hole, and then use fire-resistant The material is processed into a board-supporting fire-proof blocking material with a certain strength to ensure that it is firm after being blocked and is easy to disassemble and assemble when the cable is replaced. The plugging is dense and non-porous to effectively block smoke and fire.

What are the main properties of the insulation material of the power cable?

(1) High breakdown strength;
(2) Low dielectric loss;
(3) Very high insulation resistance;
(4) Excellent discharge resistance;
(5) It has certain flexibility and mechanical strength;
(6) Long-term insulation performance is stable.

What are the regulations for cable protection tubes?

(1) When the cable needs to be laid through a protective pipe, the inner diameter of the pipe should not be less than 1.5 times the outer diameter of the cable, and the inner diameter of the concrete pipe, clay pipe, asbestos, and cement pipe should not be less than 100mm;
(2) The bending radius of the cable tube should meet the requirements of the bending radius of the cable inserted;
(3) Each pipe should not exceed three elbows at most, and there should be no more than two right-angle bends.

How to measure the outer diameter of the cable sheath?

At five evenly distributed points on the circumference of the sheath, measure the outer diameter of the sheath and its average value. The average outer diameter is the outer diameter of the sheath.

How to connect copper core cables with different cross-sections?

Copper core cables with different cross-sections can be connected by open-back weak copper pipes and connected by soldering, or pure copper rods can be connected into copper pipes according to different cross-sectional requirements and connected by crimping.
