TECHNICAL DATA HEAVY DUTY FLEXIBLE CABLES

Construction of abc

xlpe/hdpe insulated power conductors of aluminium (neutral conductor and street lighting conductor if and when necessary) are laid together (twisted) around a high tensile standard and galvanized steel (aluminium alloy may be used) insulated or bare messenger wire to form the aerial bunched cable. This assembly is directly strung on to distribution pole/towers by means of standard hardware available in the market but care shall be taken to render the messenger wire completely insulated from earthing at any point of distribution in case of ht abc.

the xlpe (cross-linked polyethylene) insulation is black in colour and is stabilized against deterioration caused by exposure to direct sunlight and ultraviolet radiation. Xlpe is cross-linkable low-density polyethylene, which is made thermo set by special formulation from base polymer of thermoplastic low-density polyethylene. Xlpe combines the best electrical properties of ldpe and superior thermo mechanical properties.

materials

aluminium conductors conform to is:8130(class-ii)
standard high tensile galvanized steel messenger wire conforms to is:398 (part 2). Alternatively aluminum alloy messenger wire conforms to is:398 (part 4)
xlpe and hdpe insulation of power conductors specify is:7098 (part I & ii) and is:6474 respectively.

since, the tension from the current carrying conductor is totally removed by introduction of messenger wire the operating temperature of the conductor is 90 c as against 75 c of the bare conductor of the same size.

stringing:

no difficulty is envisaged during stringing of aerial bunched cables in the conventional method but care shall be taken that insulated conductors do not get damaged during installation. Dragging the abc on the ground is to be avoided. Tension to be applied during stringing shall be 25% of the breaking load of the messenger wires. This will allow line to have sag within specified limit of 1.5% of the span at the lowest ambient temperature.

jointing:

while mid-span jointing permissible for lt abc system by conventional technique, our recommendation will be to draw the line in such a way as to bring the joints at the supports. Mid - span joining is not at all recommended in the case of ht lines our recommendation is for outdoor type hv terminations only. Under unavoidable circumstances, line tapping at the support points may be allowed through suitably designed clamp connectors /pg clamps. The semi conducting screen continuity shall be maintained at all joints as far as possible to avoid fluctuations during system disturbances. The 3-phase screens may be shorted and earthed through suitable non-liner surge arrestor. Attempting to make a tap off from power conductors in the region where catenary is under tension in not recommended.

application:

aerial bunched cables can be conveniently used:

as replacement of bare lines in rural areas, in woods and in other localities & narrows streets where the space limited.
as replacement of bare lines where reliability of supply is of prime importance.
as replacement of bare lines where high degree of stability of supply voltage is of importance.
in hilly terrains where cost of erection of overhead lines or under ground cable becomes very high.
as reinforcement of existing system without increasing voltage.
for temporary supplies.

advantages:

in comparison to bare overhead power distribution lines, abc has very high reliability in maintaining services because power and neutral conductors are insulated with the best dielectric medium, resulting in the following advantages:

less fault rate on account of good protection against line and ground fault by high winds or falling trees or birds especially in hilly areas & forests as encountered in rural distribution networks.
high insulation resistance to earth in all seasons and polluted atmospheres. Negligible leakage currents and low losses.
multiple circuits of power and telephone cables could be strung in the same set of poles or any other supports like walls etc.
better adaptability to run concurrently with existing overhead bare conductor system without any interference.
high capacitance and low inductance leading to low impedance of lines.
lower voltage drop, higher current capacities. Vis--vis better voltage regulation.
longer spans and longer distance lines are possible with better system stability.
abc cables are much safer than bare conductors.
it can be over hung in dense vegetation and forests.
additional connections can be easily and quickly made with hot line connectors.
total lines costs are reduced.
maintenance is very easy.

Capcab Has Been in the Forefront in the Development of Cables for Applications Where the Fire Associated Phenomenon is of Concern. the Development of These Cables Needs the Awareness of the Environment in Which the Cables Will Be Laid and Probable Situation in Fire Conditions. Capcab Has Subjected Its Cables to a Rigorous Evaluation Under Different Fire Situations. this Development Has Been Possible By the Usage of Various Polymers and Elastomers, Designs and Composites. the Three Important Considerations in the Selection of Cables Are:- the Power Requirements that Cable Has to Meet With; the Environment and Special Requirements like Oil Resistance, Abrasion; Resistance Etc. the Possible Consequences of Fire and Liabilities in the Environment. the Cable Specification Must Be Evolved as a Compromise By Evaluating These Considerations. the Design, Construction and Testing of Frls Cables is Relevant to Technical Specifications such as Is:1554 Part I and Ii, Is:7098 Part I and Ii, Etc. in Addition, Several Special Tests are Carried of Frls Cables and Constitute Components to Fulfill the Needs of Improved Fire Performance Characteristics. Special Tests over and Above the Standard Tests, Frls Cables and Its Components are Subjected to Series of Special Tests to Fulfill the Need of Improved Fire Performance Characteristics. physical Testingr&d and Quality Control in Cable Industry Utilizes Physical Testing as a Very Important Tool. Capcab Has a Modern Computerized Tensile Testing Setup Having Facilities for Optical Extensometry, Low and High Temperature Extensometry. the Computerized Facility Enables Accurate Control On Evaluation. smoke Measurementsmoke is a By-product of Combustion, Which is Manifest By Its Opacity. Smoke However is Particulate in Nature. Hence the Evaluation is Based On Optical Methods and Gravimetric. the Testing Being Environmentally Influenced, the Selection of the Method is Done Accordingly. the Common Methods of Testing Are:- astmd 2843this Method is Designed to Test the Smoke Density in Context to a Fixed Interval of Time and Defined Environment. a Sample of the Material of Fixed Dimension is Placed On a Sample Holder and a Flame of Specified Intensity is Applied for Four Minutes. the Smoke Generated is Evaluated By the Percentage Obscuration On An Optical System Which is in the Path of the Smoke By Measurements At Intervals of 15 Seconds. a Plot of Percentage Obscuration Against Time is Made and the Percentage Smoke Density is Calculated. the Area Integration Method Actually Gives a Quantitative Indication of the Smoke Generation Potential of a Material with Respect to Time.astm E- 662this is the Latest Method of Evaluation of Smoke Characteristics Which is Based On Optical Principles But Relates to Assessment of Generation of Smoke in Flaming and Non-flaming Mode of Material. the Inference Between the Two Standards is Not Comparable Due to Environmental Differences Yet Both Serve as Comparatives for Material Behavior. 3 Meter Cubethe Test Has Been Adopted for Evaluation of the Cable as a Whole from the Aspects of Smoke Generation. Adaptations of this Technique is Done in the Uitp and Iec Standards. the Test Involves An Assembly of a 3 Meter Cube Test Chamber Where in a Meter Length of Cable or a Number of Cables are Placed Depending On Diameter. the Ignition is with An Alcohol Flame.
