In addition to its "in house" projects, the R&D maintained close links with the plastics industry. One such development to result from this connection was the use of Mathweb GRP structures. BP Technical Developments had developed a technique for producing GRP lattice structures more as a speculative general development than with any specific application in mind. The Plastics Development Unit (PDU) recognised the potential of this technique for producing emergency structures for overhead line equipment where the lighter weight of the GRP (approx 1/3 wt of a steel structure) could considerably reduce erection time and equipment, and ease transportation to site. Accordingly the PDU and the CM & EE Overhead Line Engineer stimulated a joint development programme with BP carrying out component design and production. PDU provided the loading criteria and performed site trials to assess suitability and link theory with practice thus providing valuable information for both parties. A system for a simple support structure to resemble the level crossing case has been devised and further work is being undertaken on the assessment of a full portal frame structure. |
