After the completion of installation, inspection request will be raised to the consultant to ensure accuracy and quality of work. Cable testing will be carried out afterward in accordance to approved test plan. In cables of different voltages, if the insulation is lower than the voltage run of the adjacent cable they would be installed in a separate raceway or containment.
Fire resistant cables will be installed in all fire safety corridors. Instrumentation, automation and control cables will be installed in compliance to BS or equivalent. All horizontal and vertical installation of cables to cable trays and cable ladders will be supported using approved cable tie for LV and cable cleats for MV.
Care will be taken during installation so that cables are not subjected to tension and or mechanical stresses. Pulling lubricant to be used with UL listed category and consultant approved in pulling the cables in conduit. If cables are cleated directly on the soffit, the cleating supports will be installed at regular intervals. Cable drums will be positioned as close as possible to the installation area. Care will be taken care during transportation of cable drums. Where cable rollers to be used, it will be position at suitable intervals and secure them for installation on cable tray.
For long runs where recommended tension values may be exceeded, intermediate pulling will be implemented by arranging the cable in loop Tension indicator will be provided. Where change of elevation or direction take place, cables will be supported and guided by corner type of rollers to prevent stress or damage during the pulling.
Cables will not be bended to a radius smaller than values recommended by the manufacturer. Also it will be ensure that no twisting of armored cable take place. Care will be taken to ensure that external sheath is not damaged during cable pulling. Our specialized building wire compounds are formulated to meet performance requirements while ensuring improved manufacturing efficiencies, including higher extrusion speeds. Our large portfolio of engineered products will assist with ease of installation by having a lower coefficient of friction, as well as providing exceptional abrasion resistance.
Westlake Global Compounds is in the center of one of the fastest growing cable markets and strives to lead the way in riser and tray cable applications.
We aim to develop the most innovative products for the 5G market alongside our customers. Just like the name suggests, the armored cables are heavily fortified cables that are made with special focus on protection in order to protect the cables from being cut, abraded or damaged by the external environmental factors.
The structure of armored cables is such that it contains various protective elements, i. The insides contain basic optic fibers that are protected with a steel tube. Between the steel tube and outer plastic jacket, is a flooding compound that keeps the external moisture from penetrating and damaging the fibers. The armored cables are heavily used in areas that are prone to mechanical damage. However, to meet with the inside cabling needs for any infrastructure, an unarmored cable is utilized.
Instrumentation cables are extremely rigid and tough cables that are used for inter or intra communication between the operators and the instrument available on any construction site.
Additionally, they are also used in a wired communications network. Since they have multiple central conductors, they are widely helpful in sending or receiving low energy electrical signals. Instrumentation cables are only limited to industrial level because of which they are built with strength and stealth in mind. They are available in various types but the basic structure is similar to one another to some degree.
For instance, instrumentation cables contain multiple central copper conductors that are insulated through various levels of screenings, i. PE bedding, galvanized steel wire, outer and inner sheath, PVCs, copper wire braiding, and more. The additional layer of protection makes instrumentation cables resistant to moisture, corrosive elements, chemical agents, oil, solvent, and more. Low voltage cables are specifically utilized for delivering electrical signals that have a voltage of around V for AC and V for DC.
Any discrepancies, damages etc. Material found not suitable for the project are removed from site immediately. Cables are stored with the factory packing on the flat surface with stoppers to prevent drums rolling, as demonstrated on the attachment. Protection shall be provided from direct sunlight. Wires shall be sorted and stored size-wise for easy retrieval.
Wires shall be stored in covered and ventilated place.
