MITA Technical Information
Anthority
Manufactured to comply with the requirements of BS4678: Part 4 (where applicable). All systems allow the installer to comply with the current edition of the IEE regulations.All Mita products are supplied in accordance with the stated requirements of CE marking, introduced in 1997.
Description
Body and lids are extruded from high impact, self-extinguishing rigid uPVC. Lids for all the compartments clip to the body section with MITA's proven double locking action, for additional security and to ensure they are not accidentally displaced. Angles and joint covers (where applicable) clip into position and are secured with either recessed screws or positive action clips.
Performance
Typical properties of rigid PVC are:-
- Specific Gravity (Density) - 1.35 - 1.47
- Thermal Expansion - 6x10 (-5 degrees). This is approximately equivalent to an expansion of 2mm on a 3 metre length for a temperature rise of 10 degrees. Care should be taken not to run the installation at the upper temperature continually for long periods.
- Water Absorbsion - Negligible
- Chemical Resistance - Mineral Acids - excellent, detergents - excellent, alcohols - Fairly Good but liable to attack from other solvents such as ketones, aromatics and hydrocarbons.
- Maintenance - To be wiped clean with a damp cloth only.
Fixing
The units can be neatly cut using a fine tooth tenon or hack saw and trimmed for appearance with a sharp knife or file.
Data Cable Guides
Data cable guides provide a sweeping bend radius to maximise performance of Cat6 and fibre cables as stipulated by BSEN50174-2 (CENELEC), ISO IEC11801 and ANSI/TIA/EIA568B
Data Cable Guides can be used in conjunction with the standard trunkings, angles, tees and bends and simply clip or fix into place.
Minimum Bend Radii
Minimum bend radii must be observed for all cabling to ensure it is not damaged or its performance impaired. The minimum permissible bend radius of a cable is greater during pulling in, when it is under tension, than when installed, and free from tension
BS 50174-2, Separation between Power & Information Technology Cables
In installations where the horizontal cabling length is less than 35m, no separation is required, in case of screened cabling.
For lengths greater than 35m, the separation distances apply to the full length excluding the final 15m attached to the outlet.
