Güç Dağıtımı ve Kontrolü için Kompakt Bara Sistemi Veriyolu

The Compact LX Busbar Trunking System

LX compact type busbar system fully comes from the technoloy from UK, and it's also combined with the local electricity environment, enjoys elaborate R&D, safe and reliable performance, and also attractive appearance. The product conforms to GB7251 and IEC61439 standard, with the rated voltage 1000V, rated current ranges from 400A to 6300A, 16A to 1600A plug-in current, and the max protection IP66, it can be applicable to 3P3W, 3P4W and 3P5W system etc. LX enjoys the best overal performance in low voltage busbar field, and gets a wide use in large commercial plaza, high-rise buildings, intelligent building, gymnasium, industrial factories, hospitals and other important occasion.

Main structure:
1. Total compact length (including plug-in): low impedance, low line loss, small size, save space. Fast heat dissipation capacity, low temperature-rise, long service life. Conduction heat dissipation, load capacity is not affected by installation method; no hollow structure, no "chimney effect".
2. Plug-in and joint pack are Phase Error Control designed: ensure correct installation phase sequence.
3. Automatic riveted assembly: rivets are imported from Germany, high efficiency, fast delivery, stable processing quality, better electrical continuity of enclosure.
4. Various diversion unit: layout can adapt to various site environment.

Aluminum alloy enclosure:

1. LX system adopts alloy profile as the enclosure.
2. Enjoy high mechanical strength, strong dynamic stability.
3. Light, convenient for installation.
4. Heat dissipation 3 times than that of steel.
5. Low magnetic, effectively avoid the eddy current and hysteresis losses on the impact of the bus duct system.
6. Nice corrosion resistant capability, still remains strong anti-corrosion even if the layer is scratched, has passed 1800 hours salt spraying test.

Conductor - rectangular copper or alloy bar:


1. The LXC conductor is of high purity copper (≥99.95%). The raw copper material is imported from overseas and formed to bars in our plant in China.
2. The LXA conductor is of alloy, mainly structured by hign purity aluminum bar used for electricity, and after a special treatment on the surface it can reach an impovement of high conductivity which is incomparable in respect of a pure copper bar.

Insulating materials - Dupont mylar insulation film:

The conductor is coated with Dupont mylar insulation film, with each phase double wrapped, 6 insulation layers between phases to ensure the reliability of the insulation. With insulation class B, heat resistant 130ºC, per layer withstand voltage is more than 10000V.  Dupont mylar is the professional electric insulation material recommended by IEC, no toxicity, no halide even at high temperature.

Joint pack - fast and stable:

1. The double bolt torque memory makes installation fast and stable, only 19mm ordinary wrench can complete the installation and reach to the expected torque.
2. The special butterfly spring ensure long lasting pressure equilibrium.
3. Joint pack internal conductor cross section is 1.2 times more than trunking bar section, and the double face connection can effectively reduce the contact resistance.
4. 75% installation time could be saved.

Tap-off unit- safe and reliable:

1. Plug-in feet is of "T" structure, with high elastic manganese steel piece, can be repeatedly plugged in and out more than 200 times without any deformation.
2. The feets are silver plated to effectively reduce the contact resistance.
3. The safety interlock mechanism can ensure the safty, only when the box is full in position can be switched on, and only open the door under switch-off.
4. There's patent design to avoid the plug in of wrong phase sequence.
5. Protectible cover to improve the protective level of tap off unit.

LX tap-off unit delivers the power from the busbar trunking system to a lower lever load and also has line protect function. The unit enjoys compact structure, nice shape, reliable performance, complete specifications, and can meet the requirements of different customers.

LX tap-off box design is more closer tu user, providing with built-in circuit breaker or fuse protection. The circuit breaker type is optional for user, including the switch accessories, e.g. handles, shunt tripping device, electric operation, etc.

Dimension:


Note: The above dimension is based on the size of domestic conventional circuit breaker. The specific tap-off box size will be adjusted according to the internal configuration.

Installation method:





Technical data:
Basic data
Short-circuit ratings



Conductor configuration:

LX busbar systems provide various conductor configurations to meet different requirements and systems.

Enclosure as PE: in case serious grounding fault occurs, the nonmagnetic Al-Mg alloy enclosure could be the grounding conductor and the whole power system will connect with the earth directly to make sure the security.




Producton Equipment:

• Automated assembly line, BOLLHOFF riveting process

LX busbar system assembled by BOLLHOFF automatic riveting line from Germany. The riveting line from Germany effectively guarantees the stablility of processing quality and consistency, and greatly enhances the overall strength and electrical conductivity. In addition, its efficient uninterrupted production capacity enjoys the fast delivery.

We fully use the various advantages not only of ourselves, but also all over the world, we have behinger sawing machine from Germany, euromac bending machine from Italy, Hontex layer thickness meter from Germany, TRUMPF punch machine from Germany...

• Automated inspection system

Shanghai Zhecheng Electric fully implement the "Zero Tolerance Defect", the advanced busbar automatic inspection line garantee 100% performance test, including insulation resistance testing, power frequency withstand voltage test, grounding resistance test, etc.

Calculation and Selection:
To make the busbar system be the most suitable product we also provide the calculation and selection services using scientifics methods and formulas to obtain the exact data, such as the voltage drop, the rated current, the reduction, the minimum short-circuit current etc.

The impedance values (including the resistance ractance) mainly comes from: test results, the calculation results, simulation system. We have the form of various "R" and "X" of LX in details.
