The Ideal Reticulation Pole
The high strength-to-weight ratio of prestressed electrifi cation poles sets them apart from poles made of other materials. Prestressed concrete facilitates poles which are functional yet relatively light, making them convenient for contractors to handle.
Appearance
• The rectangular tapered I-Section design and the light grey concrete in which the poles are cast are pleasing to the eye.
• High strength, high density concrete has a smooth fi nish which is resistant to the elements.
Durability
• Experience worldwide demonstrates that during their lifetime, prestressed concrete poles are maintenance-free.
• Concrete, unlike other materials, suffers no loss of strength over the years, being resistant to insects,
fire, decay and corrosion.
• Concrete poles requires no chemical treatment, thus avoiding the risk of soil contamination.
• Unlikely target of vandalism or theft as concrete poles have no resale or scrap value, nor can they be used to make fi res or used as building material.
• Manufactured to Eskom DTC 0106, various SABS and OHTE specifi cations at INFRASET’s ISO 9001:2000 accredited factories.
Strength and Availability
• Prestressed concrete poles are resilient and will recover from the effects of a greater degree of overload than any other type of structural material.
• The poles have a crushing strength of 60 MPa after 28 days and are fully prestressed.
• They are manufactured in a wide range of strengths and sizes to fi ll most requirements in MV and LV lines.
• By choosing the appropriate pole and foundation design, some deviation and termination poles can remain without stays, thereby saving space and eliminating clutter.
• Prestressed concrete poles are manufactured to guarantee maximum strength, which takes the guesswork out of line design.
Added features
• Poles can be cast with internal conduits for use in applications such as street lighting, security cameras, etc.
• Poles are supplied with standard holes.
• Earthing bars with 12mm sockets at standard points can be cast into the poles on request.
• Poles can be stockpiled indefi nitely in remote places without concern for theft, decay or corrosion. |
