Product catalog summary
Conduit Systems Overview
This document provides comprehensive details on various conduit systems, including round and oval PVC-U conduit systems, MT Supertube, and associated fittings. These systems are designed to meet LS0H (Low Smoke Zero Halogen) and EMC (Electromagnetic Compatibility) compliance requirements.
Specifications
  • Round Conduit and Fittings: Available in light and heavy gauge, made from high-impact, self-extinguishing PVC-U, compliant with BS 4607, BS EN 61386-1:2008, BS EN 61386-21:2004+A11:2010, and BS EN 61386-25:2011 standards.
  • Oval Conduit and Fittings: Designed for cable protection in shallow voids or walls, made from high-impact PVC-U, recyclable, and non-flame propagating.
  • MT Supertube: A three-layer heavy gauge conduit with polyethylene layers and an aluminum core, offering excellent EMI screening, suitable for rail, marine, and tunnel applications, compliant with BS 7671 and BS 8436 standards.
Product Features
  • Round conduit fittings include reducers, inspection elbows, tees, bends, couplers, and more, available in various sizes and packs.
  • Oval conduit fittings include clips, adaptors, and connectors, designed for easy installation and cable protection.
  • MT Supertube fittings include metal and polycarbonate options, such as adaptors, couplers, and boxes, designed for EMI protection and compliance with wiring regulations.
Technical Information
  • Conduit systems are available in standard colors: white, black, and red (selected items).
  • White conduit lengths are manufactured using over 95% recycled material.
  • MT Supertube offers zero waste with continuous lengths up to 100 meters, reducing the need for fittings and preventing water ingress.
Case Study
The document includes a case study on the use of MT Supertube in the Tate Modern's Switch House extension, highlighting its flexibility and cost-effectiveness compared to traditional galvanized conduit.
Overview of MT Supertube Conduit System
MT Supertube is a conduit system designed as a time-saving alternative to traditional galvanized steel conduits. It combines the strength of metal with the flexibility of PVC-U, offering fast installation and easy handling due to its coil form. The system is maintenance-free and can be buried in concrete, detectable by a CAT detector.
Material Composition and Benefits
The MT Supertube features a three-layer construction with Low Smoke Zero Halogen (LS0H) polyethylene and aluminium, providing excellent EMI cable protection and resistance to temperature extremes and chemicals. It is lightweight yet strong, facilitating quick installation and easy storage.
Cost Efficiency
Using MT Supertube can significantly reduce costs compared to galvanized steel. For example, using 100m of 20mm conduit with 8 off 90° bends, MT Supertube costs £905.79, which is 54.23% cheaper than the £1979.20 cost of galvanized steel, saving £1073.41.
Technical Specifications
MT Supertube offers high shielding effectiveness across a wide frequency range, protecting data, telecoms, and signal cables from interference. It is constructed with a seamless aluminium tube between two LS0H polyethylene layers. The system is compliant with various standards, including EN 61386-21 and IEC 601196-1.
Fire and Mechanical Performance
MT Supertube exhibits excellent fire performance with a high oxygen index and flammability temperature. It passes cold temperature impact tests and flame propagation resistance. The mechanical properties include a minimum bend radius, specific wall thickness, and weight per metre, ensuring robust performance.
Installation and Environmental Considerations
PVC-U used in MT Supertube is flame retardant, self-extinguishing, and 100% recyclable, with products manufactured from up to 100% recycled material. The system requires a separate earth cable due to its all-insulated nature.
Conclusion
MT Supertube is a cost-effective, efficient, and environmentally friendly conduit system suitable for various installations requiring halogen-free products and robust EMI protection.
