Busduct system passes the international
test
The Anord/Henikwon SCM Busduct system has recently been tested at 100kA for 2.7s in accordance with IEC standards and verified at an ASTA test station.
The Anord/Henikwon SCM Busduct system has been established in the market since 1983 With a strong global reputation in the industry for providing class-leading, innovative, technically advanced designs
Henikwon is recognised as a world leading independent manufacturer of Busduct systems.
In response to the growing demand for fully tested very high current systems the SCM 6300A range has recently been tested at 100kA for 2.7s in accordance with IEC standards and verified at an ASTA test station.
The tests were performed to IEC60439-2:2000 and BS EN60439-2:2000 Clauses 8.2.1, 8.2.2, 8.2.3, 8.2.10, 8.1.12, 8.2.13 and 8.2.14 and show that the product been successfully tested for: temperature-rise limits; dielectric properties; short circuit withstand strength; verification of clearance and creepage; verification of degree of protection to IP54; verification of structural strength; mechanical crushing test on the short sample; resistance of insulating materials to abnormal heat; and verification of resistance to flame propagation.
The SCM Busduct is one of the few systems in the world that can offer clients the security of completely tested products for current rating, fault performance combined with high IP ratings and excellent resistance to flame propagation.
Available in both copper and aluminium with current ratings from 400 to 8000A, the system has a non-ventilated, compact, sandwich type construction and is totally enclosed for operation indoors or outdoors with IP ratings of IP54 and IP68.
The conductors are coated with a 1.6mm epoxy insulation applied directly to the conductor by a specially designed extruding process and is bonded at high temperature under high pressure to prevent the forming of any voids.
This makes the system especially suitable for operation in high temperature applications where damp humid climatic conditions occur.
The compact design is ideal for high power applications such as transformer to switchboard connection, power distribution in industrial installations and rising main installations in large high rise buildings.
From an economic point of view the supply of power in large buildings and factories is more competitively provided by a busduct system rather than by conventional electric cables.
The ease of installation and the strength of the SCM busduct over long runs with fewer fixings per metre than are required with cable brings a significant reduction in installation time and cost.
Busduct is also much more versatile as installations can be modified very quickly when additions or relocation of plant is required.
SCM can be configured horizontally as used typically in factory installations or vertically as used in commercial buildings for rising main systems, or any combination to suit site conditions.
The system has been designed to be very flexible and can be reused, relocated and extended utilising standard components.
Individual lengths can be removed without affecting the integrity of the system and replaced with other sections incorporating bends, tee-offs etc.
In both manufacturing and commercial installations, stability of supply can be a critical factor.
With the SCM systems Sandwich, low impendence construction superior volt drop characteristics can be guaranteed avoiding adverse supply disturbances, essential when the installation contains voltage sensitive IT equipment.
The potential weak point in a Busduct is at the joint.
With the SCM maintenance free joint system this problem is eliminated by the use of a high strength torque bolt with an outer head which breaks free when the designed ultimate torque level is reached.
The joint design also permits safe testing of joint tightness without the need to de-energise.
As world growth in electricity demand continues and loadings in individual buildings increase the SCM system will be at the forefront providing solutions to new demands as they occur in the world energy market.
