Mechanical properties |
|
Compressive strength |
|
The enclosure’s wall/base is subject to compressive loads in use and needs to withstand specific loads | 80MPa typical |
Flexural strength |
|
Affects site handling and when enclosure is installed in areas where encasement and soils are suspect | 24MPa |
Tensile strength |
|
Generally only relevant to an enclosure’s lid/cover | 20MPa |
Thermal/Electrical properties |
|
Water absorption |
|
The enclosure’s wall/base is designed to keep moisture away from its contents where possible | < 5% |
Electrical resistivity |
|
The electrical insulation capability of an enclosure’s materials | 1 x 108 Ω/sq |
Freeze thaw |
|
Inability to withstand freeze-thaw cycles causes surface spoiling and leads ultimately to an enclosure’s failure | Modulus of elasticity unchanged |
Coefficient of expansion/contraction |
|
Excessive movement between enclosure’s wall/base and encasement materials (usually concrete) creates unwanted stresses which may lead to failure | 10 x 10-6 deg C |
Water vapour transmission |
|
WVT is a measure of water vapour flow through a material. Passage of water vapour may be critical in some instances | 1 x 10-4 gm/s. Mn |
Surface properties |
|
Surface burning |
|
Cable enclosures are often used around petrol stations, chemical processing and interior applications and may be subject to fire. They should be nonflammable and not give off fumes or smoke | Non combustible. Ignitability: P Fire propagation: 0 Flame spread: Class 1 Fire resistance: 1 hour for 10mm thickness |
Weathering |
|
The majority of cable enclosures are used in exterior applications. Ability to withstand adverse weather will ensure long service life (erosion, UV degradation, etc.) | UV Stable Good as H.S. Concrete |
Chemical Resistance |
|
Cable enclosures may be subject to acidic or soils | Excellent. Equivalent to 80MPa concrete |
