OVER HEAD CONDUCTOR

Installation Guidelines

High Temperature Aluminum Conductors Type ACSS & ACSS/TW

In general , ACSS & ACSS/TW conductors can be installed adopting the same method of

installation as that of ACSR . However because of the special characteristics of this type of

conductors , the following additional precautions are recommended during installation.

1. ACSS & ACSS/TW conductors are not to be dragged across bare ground or other hard

surfaces to prevent surface scratches/scuffing because the conductor is made up of

fully annealed aluminum strands in the outer layers.

2. The conductors are to be installed only by Tension Stringing methods. Conductor pay-

offs are to be put in line with bullwheel tensioner to avoid scuffing of conductor

surface against adjacent layers in the reel.

3. Tensioner wheels having a diameter at least 35 times the conductor diameter at the

bottom of the grooves are recommended to be used. Multi groove tensioners with

lined groove s are recommended. Usage of single V-groove tensioner may be avoided

as it can cause damage the conductor .

4. To facilitate pulling of the conductor , a washer and compressed steel sleeve shall be

attached to the leading end of the conductor. The aluminum strands are to be cut to a

length approximate to that of the steel sleeve from the end of the conductor.

Thereafter inserted a washer on the exposed steel core to press against the cut ends

of the aluminum strands. The washer outsider diameter should be equal to the

conductor diameter. Thereafter steel sleeve shall be compressed over the steel core.

5. Kellems grips should be properly sized to the conductor dimensions and must be

double banded on the open end. The bands are to be covered with tapes to prevent

damage to sheaves.

6. All come-alongs and grips shall be designed and tested for the size and type of the

conductor being installed. Come-alongs should be clean and well lubricated . The bolts

should be snugged- up and tightened with repetitive passes applying the full torque

recommended by the manufacturer.

7. Open sided parallel jaw grips should be of size close to the conductor to minimize the

distortion in strands. Usage of grips designed for multiple range/ size of conductors

are to be avoided.

8. It may be necessary to use tandem grips or core gripping methods for certain high-

tension applications.

9. The installation of the conductor is to be carried out strictly in accordance with

Specification IEEE-524-2003 “IEEE Guide to the Installation of Overhead Transmission

line conductors” unless otherwise specified.
