MEDIUM VOLTAGE BUSBAR TRUNKING SYSTEMS
BUSWAY 'CR'
Joint Coupler
   
Compliance of Design - Standards Busducts are designed and manufactured in compliance with:
IEC60439-1: 1999 Low-Voltage Switchgear and Controlgear Assemblies
  IEC60439-2: 2000 particular requirements for busway
  BSEN60439-2: 2000, BS5486-2: 1990, AS439-2-2002, UL-857
  IEC60529: 1989-11 Degree of Protection
  IEC60947-2: 1995 Circuit-Breakers
  IEC60331 & BS6387 Resistance to Fire
  IEE/IEEE Wiring Regulation
  Seismie (Earthquake) Protection
Excellent advantages 1. Epoxy E-coat provides high dielectric strength in excess of
    14KV/mm. The pre-heat process removes all moisture or air
    pocket that causes internal partial discharge and electrical
    failure.
  2. Busduct resin is fire resistant comply to IEC331 & BS 6387
    standards and is self flame extinguishing.
  3. Maintenance free busducts.
  4. Each busway joint allows two busducts sections joining together
    with adjustable length spot on or extend up to 20mm longer.
  5. After curing under controlled conditions Cast Resin formed a
    rigid and hard material that is resistant to damage during
    handling or installation.
  6. Thermal expansion of epoxy E-coat, Cast Resin and
    conductors are of the same magnitude.
Electrical Dielectric
Insulation		 1. 3.6KV, Ud=10KV, Up=20KV/40KV BIL
  2. 7.2KV, Ud=20KV, Up=40KV/60KV BIL
  3. 12.0KV, Ud=28KV, Up=75KV/95KV BIL
  4. 17.5KV, Ud=38KV, Up=75KV/95KV BIL
  5. 25.8KV, Ud=50KV, Up=95KV/125KV BIL
 
Types of Busbar - Configuration Busduct are constructed with high conductivity conductors:
  Composition Conductivity
COPPER 99.98% >98% IACS
ALUMINIUM 99.98% >61% IACS
Phase busbar: Single Phase, Two Phase or Three Phase
Neutral busbar: 50%, 100% or 200% of Phase busbar
Earth busbar: 50%, 100%, 150% or 25% on both side
Cast Resin Insulation Supports Consists of high grade epoxy resin mixed with inert mineral fillers, is halogen free and does not exit toxis gas.
Degree of Protection Up to IP68 of IEC529
Superior Advantages 1. Busway resin is fire resistant comply to IEC331 standards
    (3 hours at 750°) & BS 6387 (3 hours at 950°)
  2. Cast Resin formed a rigid and hard material that is resistant
    to damage during handling or installation.
  3. Joint is designed such that it is not possible to encase without
    first tightening the joint locked nut with the correct torque.
