## Summary

The Strathclyde Partnership for Transport (UTILITIES) is planning a procurement process for the 'Supply of Third Rail Insulators' in Glasgow, UK. This tender is in the planning stage and the future notice date is 2022-11-01. The procurement process is open to businesses in the Transport industry category. The buying organisation is a public body and the procurement method is a tender.

This opportunity for business growth involves supplying third rail insulators for the Strathclyde Partnership for Transport (SPT) Subway. Businesses in the utilities sector, especially those with experience in providing similar parts under the Utilities Directive, would be well-suited to compete. The tender aims to engage potential suppliers and replace parts on an 'as required' basis, allowing for additional similar parts to be included in the contract.

## Notice

open to the material, currently polymer but must meet the standard. If SUPPLIER proposes non-polymeric third rail insulators, a modified type test may be proposed for PURCHASER approval. requirements for supply of third rail insulators and associated components for use in the Strathclyde Partnership for Transport (SPT) Subway. The insulators shall be suitable for use in the Subway 600V dc traction system and for use in Subway traction system as modified to 750V dc. The conductor rail system is designed for current collection at all speeds up to 58kph and under certain conditions a limited degree of arcing can occur. The insulators shall withstand resulting transient effects. The insulators shall withstand the impact, shocks, strains, stresses and vibrations associated with anchored or unanchored conductor rails, which are subjected to longitudinal, vertical and lateral movements. The insulators shall withstand the effects of short circuits of varying severity as are likely to occur due to the system environment. Third Rail Insulators shall accommodate Subway steel third rail and maintain it in orientation with top surface nominally parallel with plane of rail. The steel third rail has an 'L' section. There is some variance in third rail cross sectional profile which shall be accommodated. Support Brackets Insulators for use in the system shall be suitable for installation on existing support brackets When installed within a support bracket assembly the insulator shall be shaped and dimensioned to achieve: - Third rail top (contact) surface height of 307mm (+/-5mm) above top of rail - Third rail horizontal offset of 463.5mm (+/-5mm) from running edge to inside edge of third rail The insulator shall be designed for minimum withstand voltages of 25kV dc (dry) and 3.5kV dc (wet). the insulator colour shall be proposed for PURCHASER acceptance and shall not be green, amber or red. The insulators shall be suitable for use in a sub-surface environment and shall be Low Smoke Zero Halogen (LSZH) type.
