This routine (CandS) is intended for use on distribution systems employing pin type insulators throughout the strain section, thereby creating "mechanically independent" spans. The principles, however, may be applied to transmission systems subject to reasonable and competent assessment of the application.

Calculates the line profile for a maximum 6 circuit and 10 span strain section. 10 spans generally equates to the practical cable length carried by a standard cable reeler. Distribution strain sections do not often exceed these circuit and span numbers.

Provides for a strain and a termination pole.

Stays and tee-offs will be added as a future construction.

Terrain levels can be loaded from a surveyor's .csv file to allow display of the ground profile and conductor ground clearance.

Calculates the conductor tension and the pole tip load for sustained (no wind) and ultimate (maximum wind) conditions.

Calculates the uplift at each conductor attachment and uplift for the whole pole.

Calculates the stringing tables for construction of the strain section at everyday and other typical temperatures.

In the spirit of Tim Burners-lee (father of the WWW), this routine is available free of charge to all. Users can amend/modify, but not save, the strain section. Some sample projects may be loaded and viewed/amended, but not saved, by logging-on at: "CandS" / password: "CandS". To access the database function to save/store/load project data values, purchase a subscription at "Subscribe" ($AU100.00/setup & $AU25.00/year). A logon, password and Excel survey sheet will be provided. 20 projects can be saved.

A subscription will support hosting costs and future development.

Please report any bugs or comments to jacoservices@eper.com.au.

As this routine requires extensive data input, use of a desktop PC is recommended. The routine has been developed and extensively tested on Mozilla Firefox. All other popular browsers appear to operate satisfactorily.
