Frequently Asked Questions
We manufacture the following types of cables:
- LT Cables of voltage grades; 250/440, 300/500, 450/750, 600/1000
- Volts and up to 1900/3300 volts
- Flexible and special cables both in Shielded and Unshielded form
- Aluminum Overhead Conductor (AAC)
- Aluminum Conductor Steel
- Reinforced Aluminum Conductor Steel (ACSR)
- Overhead Bare Copper Conductor (OHBCC)
- Tinned Copper Conductor
- All our cables are manufactured with PVC, PE, LSZH (low smoke zero halogen) and XLPE (cross link polythene)
General wiring cables and 2 Core, 3 Core, 3.5 Core and 4 Core, Copper Conductor/PVC insulation/PVC sheathed 600/1000V are available in ready stock.
Typically it takes one to two weeks (depending upon the type of cable, stock position and quantity required).
Fast Cables has an edge over others due to several factors. Fast Cables offers the following:
- Products manufactured under ISO 9001 Quality Management Systems and Procedures
- 100% conductivity and insulation according to BSS and IEC Standards
- Trouble free operation during electrical operations
- National and International Certifications
- Direct supply and services to customers
- Focus on quality and reliability
- Customer Orientation
All our products are under warranty in accordance with the 17th Edition of IEEE Wiring Regulation for any manufacturing fault. Manufacturing of our product is in accordance with BSS and IEC Standards and Quality Management System. Product life may be more than 15 years.
We sit amongst the top few leading companies in the cable industry of Pakistan, with a reasonable share in export market as well.
We require 100% payment before delivery is made following inspection and testing at Fast Cables’ premises.
All our cables are Fire Retardant. The PVC used for installation and sheath has self-extinguishing properties. This helps in stopping the propagation of fire.
However, we can manufacture 100% Fire Resistant (FR) cables, meant for highly specific areas, on customer demand as per the recognized international standards.
There is no connection between the purity and the hardness/softness of the copper. Copper having 100% conductivity might be hard due to wire drawing while passing through different dyes, whereas the same copper might go soft while passing through annealing process.
After a type test is successfully performed on a certain cable with a specific conductor cross sectional area and rated voltage, that type approval is valid for same cable type with other conductor cross sectional areas and/or rated voltages satisfying the conditions as per the IEC specifications.
Discharges in a cable are caused by the breakdown of gas contained within the voids in the insulation. These tiny discharges release the electrical charge which can be detected using highly sensitive equipment. The voltage at which the breakdown first occurs is known as the discharge inception voltage and the charge is measured in Pico Coulombs (pC). These discharges can cause cable failure in service, therefore it is essential to detect these during routine tests of each cable.
Specifications for MV polymeric cable require measuring any partial discharge and defining the maximum level of acceptable discharge at particular test voltages. However, any discharge detected should be identified and eliminated even if it is below specification limit.
This is the method used in Australia, UK, Asia and Europe to indicate the voltage rating of a cable. The first number indicates the voltage rating of the insulation to ground and the second number indicates the voltage rating from one insulated conductor to another insulated conductor. Generally the second number is used if a cable is referred to by one voltage.
For example, a 19/33kV cable is often referred as a 33kV cable.
This is the minimum thickness of insulation required on the cables to offer a practical level of resistance to mechanical damage. If such thickness is not used to insulate 240 volts, the covering will be easily damaged.
