Fire Barrier

During Fire, temperatures around busway penetrating from wall/slab, can go up in excess of melting temperature of Material used for Housing, Conductors (e.g. Aluminum, Copper). Such excess temperatures can cause melting of enclosure and conductors, thus creating deformities/voids in sections (walls or slabs) from where busways are passing through. These voids can allow, transfer of smoke and fire from one area to another, which can result in further damages/harms

Thermal Expansion

Considering effects of thermal expansion, use of Expansion Joints is recommended in Busway Systems. They become essential when busway systems cross building expansion joints. Long straight runs where both ends are connected in fixed positions also require expansion joints. Flexible conductors inside the expansion joint allow/accommodate movement caused due to expansion.

Straight Feeders, Plug In and Tap Off Section

Feeder Busways Offered by us are suitable for Indoor and Outdoor Installation. Busway Feeders for outdoor application, are provided with additional covers, this alongside design of enclosure ensure the integrity of protection required against ingress. According to application and site conditions, client can choose these feeders with IP65, IP66 and IP67 Degree of Protection for outdoor application.

Proven Design for Joints

Joint facilitates the physical and electrical connection between busway units to complete point to point distribution system. They also play an important role in ensuring satisfactory performance of the system. Under normal current carrying conditions, heat is generated at conductor contact area due to their contact resistance. Effective management of this heat, either by reducing or transferring it to the external environment is essential for the safe operation and extended the life of the entire system.

Plug in Box features for Safe, Reliable and Easy Operations

Plug in Contacts are Maintenance Free, these silver plated plug in contacts have been specially designed to maintain proper contact pressure with less resistance throughout the life of busways.

Base insulator, facilitating mounting of Plug in contacts on the rear side of plug in box and termination of cables from Protective Device, has slot and rib structure in “C” Shape to offer mechanical and electrical protection to plug in contacts during installation and service. It also acts as a guide for proper insertion and removal of plug in box, while in use with plug in feeders.

Automated Electrostatic Coating

The automated Electrostatic coating uses special spray guns to ensure uniform thickness of insulation with a great reliability to perform. It also prevents entry of moisture, chemicals during coating operations and provides optimum strength to insulation achieved by coating. Properties of Epoxy, resulting in the smoother finish after undergoing this process help in achieving closer conductor spacing, which is essential for better performance of Busways having sandwich type assembly.

Unique Structure

Specially developed enclosure design, involving 1.6 mm thick sheet steel offers excellent strength to withstand electrodynamic forces originating during short circuits and can act as an integral ground. Larger surface area offered vide this design ensures faster transfer of heat resulting lesser temperature rise and increase in life of insulation, which in turn extends service life of entire system. In addition to this, housing design and its assembling method retains adequate position of conductors, vital for ensuring safe connection of units during installation.

Assembly Design

True Sandwich Design achieved with the help of precise fabrication of housing and perfectly insulated conductors, eliminate pathways for propagation of Flame, Gas, Smoke referred to as “Chimney Effect”, thus making Sandwich Busways Safer.

Assembly of precisely fabricated housing components is done in such a way that desired Ingress Protection is maintained without any additional welding work.

Conductors

Wilmar busway systems, demonstrate their excellence in performance also due to careful selection of conductors, from globally reputed suppliers. Copper Conductors with Tin plating are available as standard, Silver Plated conductors can be offered upon request. These conductors in round edge comply to JIS, ASTM Standards. Copper Conductors with 99.9% Purity and 100% Conductivity, are available in standard offerings. Our QA and Test Labs, are equipped with facilities to check copper purity, resistance and other chemical, mechanical properties of conductor material essential for achieving best performance of our system.

Smart and Intelligent Features

In sandwich busway systems Mechanical Interlocks and special joint bolts ensure error free and reliable connections to prevent hazards like temperature rise due to loose connections. Furthermore, Temperature Alarm Controllers can be useful to monitor healthiness of system and initiate preventive measures, incorporation of this feature benefiting our customers is possible due to design & patented technology, which has been developed at our research Centre. This feature has been admired by many of our customers, consultants and they have conferred “Smart & Intelligent” title for our busways.

Superior and Reliable Insulation

Durable Epoxy Insulation having longer service life, has been used for Conductors of “Wilmar Sandwich Busway Systems”. Benefits of Epoxy, such as Resistance to Water, Moisture, Chemicals, and Mechanical Impact besides dielectric strength, flame retardant properties make them preferred choice as insulation materials. While selecting insulation material, we have also given consideration to factors playing vital role in ageing of insulation. Some these factors are electrical (creepage currents, partial discharge, interfacial processes), Chemical, Thermal, Mechanical (Vibration, Shock, Impact), environmental (UV Radiation, Exposure to Salt Fog).

Insulation Process

Our plant is equipped with state of the art coating machines for applying insulation on conductors. Selection of insulation coating machine, has been done based on coating process - which vary based on Pretreatment for Conductor, Type of Insulation Material, and Application Process & Sequence. These machines not only ensure production of insulated conductors with best quality and durability, but also can handle increasing demand by producing them quickly in shortest possible time. This makes us feel proud, about our capacity to cater to larger scale projects with guaranteed quality of products.
