Busway Schneider
Introduction
The busbar trunking system (from 800A), both feeder and plug-in, shall be sandwich construction. All busbar trunking products and fittings (straight length, elbow, tees, flanged ends, cable tap box and circuit breaker, etc.) shall be in accordance with IEC 60439:2005 or UL857 and from the same manufacturer as the busbar trunking system. The degree of protection of the busbar trunking system should be IP54 in accordance to IEC 60529.
Rated operation voltage of the busbar trunking is 1000V. 3 Phase, 4 Wire with 50% capacity continual integral/internal earth busbar. The neutral conductor should have the same cross-sectional area as the phase conductor (3P 4W 100%N + 50%E). The earth busbar must be one continuous piece without bolting on housing.
Application
Busway is used to transmit power instead of conventional power cable.
1. Housing
The busbar trunking housing shall be constructed of code gauge steel and aluminum to reduce hysteresis and eddy current loses and shall be provided with a suitable protective finish of ANSI 49 grey epoxy paint.
The busbar trunking housing shall be totally enclosed non-ventilated for protection against mechanical damage and dust accumulation. And it shall pass at least 500 hours salt spray test to ensure the anticorrosion ability.
The totally enclosed housing shall be manufactured by the busbar trunking manufacturer. Modifications of busbar trunking to make it totally enclosed by other than the busbar trunking manufacturer voids the manufacturer’s warranty. Busbar trunking so modified is unacceptable without the written consent of the manufacturer.
2. Busbars
Busbars shall be of hard drawn sliver-plated high conductivity copper of 99.9% purity or aluminum with bimetal cladding utilized Molecular Fusion technology
There shall be no bolts passing through the busbars of the busway
3. Insulation
Each busbar shall be insulated with Class B (130 ℃ DuPont Mylar) or Class F rated (155℃ DuPont Melinex) polyester film. Epoxy insulation is not allowed.
The temperature rise at any point of the busbar trunking enclosure shall not exceed 55 degree Centigrade rise above ambient temperature when operation at rated current.
4. Support of busbar Trunking
Hanger spacing shall be noted on layout drawings and shall not exceed manufacturer’s recommendations.
Indoor feeder and plug-in busbar trunking shall be approved for hanger spacing of up to 3 meters for horizontally mounted run and 4.88 meters for vertically mounted runs. Outdoor feeder busbar trunking shall be approved for spacing of up to 1.5 meters for horizontally or vertically mounted runs.

Transformer
Introduction:Great progress has been made in the development and improvement of distribution transformers over the last decades.The application of high quality insulation material and suitable selection of the coil structure for high stress have contribute to the development of LS CAST RESIN Transformers. The LSCAST RESIN Transformer has succeeded in combining the advantage of oil-filled and conventional dry type transformers, which are fabricated with anepoxy resin. The windings are completely embedded under vacuum conditions.This casting method makes it possible to assure void-free epoxy penetration of both the inner layer and turn to turn insulation.ApplicationLS CAST RESIN Transformers canbe used in various fields.Here are just a few possibleapplications.● Indoor and outdoor unit substations● Off-shore flatforms● Commercial buildings● Hospitals● Shopping centers● Water supplies● Traction systems● SCR Power supplies
