Phase to earth voltage Uo: The core technologies inproduction processes, material applications and logistic procedures were provided by Germanexperts with key functions being managed by German engineers.
You can publish your book online for free in a few minutes! When the end caps have been removed theunprotected ends of the cable should not be exposed to any kind of moisture. In special environments, the appropriate regulations and codes of practice should beobserved. Roll in the direction shown by the arrow. From start up with wire drawing lines to extrusion lines, to assembly machines up to the laboratories and the final test fields, all technical equipment is provided with the highest European standards of electronic control equipment and measuring devices which insures that the requirements of different quality standards are met.
The Armouring type couldbe: Voltage drop V I: High Performance of the product and service through cooperation between experienced staff from Germany and local experts who are aware of the local market requirements and the highest international standards of cables manufacturing.
Create your own flipbook. For cables specified in this standard, a longer period, not exceeding 8 h on any occasion, can be tolerated.
Such tape s bzhra bind the cores together and prevent them from opening out,acts as a separator between different polymers used in a cable and works as a heatbarrier between the cores and the extruded bedding.
No breakdown should occur. Such protrusions into the insulation or into the semi-conducting layer increase the localized stress that may exceed the long-term breakdown cabels of the insulation, so the semi-conductive layer is acting as a stress control layer. The factory extension under construction is more than 8,sqm. To do so, Bahra Cables Company produces a versatile product range cover most of our customer needs: Single-core cables are suitable for d.
When testing is required after cables have been in service,regardless of service duration, Bahra Cables Company- Technology Department should beconsulted for the appropriate test conditions, which depend on the individual circumstances.
For the proper function, all master data materialproperties, dimensions, etc. During the test, the voltage should be increased gradually to the full value and maintainedcontinuously for 15 min. In particular, dangers may arise during the removal of steel binding straps andduring the removal of retaining battens and timbers which may expose projecting nails.
By keeping such standard of installation and operation, Low Voltage cables can survive in service for a time of 25 years or more without failure. Capacitance to neutral 9. The basis of the standard conditions is the climate conditions of the Kingdom of Saudi Arabia, which are: Read the Text Version. This isimportant in wet or other aggressive environments. Physical Damage during operations.
The cablds duration of earth faults in any year should not exceed h. The protective cable end cap should not beremoved from the ends of the cable until immediately prior to termination or jointing, especiallyfor cables that do not have extruded bedding.
It excludes transient voltage variations, due, for example, to lightning impulses, fault conditions and rapid connection of loads.
Additionally, other products described in seperate publications covers: Diameter over insulation mm d: View in Fullscreen Report. The cables have to be selected and installed as per the recommendation mentioned below.
Bahra Cables – Products Catalog with Cable Finder
To calculate voltage drop as the following: Conductor required cross sectional area. As Insulation treeing is uncommon problem for LV cables, the chance of electric break down is very minor. Flat Touching A Formation Approx.
It specializes in Manufacturing and Distributing Electric Cables. Product quality complying with the local and international standards 2.

Bahra Cables Company is committed to the production of the best product quality and service,utilizing cutting edge European Technology in its manufacturing. A layer of graphite coated is applied upon customer request. Load current A R: Constant depends on number of wires of conductor d: A non-hygroscopic polypropylene filler is applied between laid up cores to providea circular bahda to the cable.
Voltage between phase and earth VC: The volume resistivity of thisexternal layer is limited to meter-ohms. The nominal system voltage U, up to 1. Medium Voltage updated LowRes.

If the cable is not suitable for wet applications and the underground water engrossed inside it,replacing the defected section from joint to joint cablee the recommend solution.
Bahra Cables Factory occupies over ,square meters of prime manufacturing space together with associated design offices, laboratoriesand storage area.
The values given in the tables are for one circuit installed thermally isolated from other circuits or any other heat source. A 2- Laid in free air both end bonded Trefoil Formation Approx. Metallic screen type copper tape or copper wire and area copper wire screen 4. This way, full traceability will be guaranteed from production start to end, by being able to follow up the machines involved and the material used.
