The busway, as an important main line for power distribution, is now being used more and more widely. CG BUSWAY: "Only by selecting high-quality busways can we effectively ensure the safety of our lives and property." There are countless examples of serious accidents caused by the use of inferior busways.

For instance, a domestic bread supplier once chose a certain brand of busway at a low price for the upgrade of their factory equipment. However, due to the problem of cutting corners in the production of this brand of busway, a serious safety hazard was hidden. After some time, more than 30 production line machines were damaged due to short circuits in the electrical system, ultimately leading to a major safety incident in which the entire factory was burned down.

The embankment that stretches for a thousand li can be destroyed by an ant hole. No one wants a major safety incident to occur, and what we need to do is to prevent it in advance. CG BUSWAY reminds: Only by choosing high-quality bus ducts can we truly ensure the safety of our lives and property.

Next, CG BUSWAY will show you the chaos in the busway industry.

一、The chaotic scene of the bus duct left you stunned.

The surface of inferior bus ducts looks great, but the inside is actually in a terrible condition. All of this is a deceptive tactic played by inferior manufacturers to cut costs and deceive consumers, but it poses a real potential safety hazard for consumers.

The market for bus ducts varies in quality; some manufacturers often attract customers with the "lowest price." CG BUSWAY can easily list some common issues that customers encounter when selecting bus ducts:

1. Copper at both ends, aluminum in the middle.

Aluminum has poorer conductivity than copper and is also cheaper. Some manufacturers, in order to save costs, deceive customers by using aluminum bars instead of copper bars in the middle of the busway, leading to safety hazards in the customer's electricity usage.

2. Poor Quality of Insulation Material

Some manufacturers may use inferior insulation materials to wrap the conductors of the busway, such as heat shrink tubes supported by low-grade materials or polyester sleeves with low ratings. This results in insufficient insulation and poor heat resistance, which can lead to overheating and short circuits in the busway, ultimately affecting the overall lifespan of the busway.

3. Welding of Flexible Connectors

If flexible connectors are welded together, it is more likely to cause oxidation, leading to heating, which in turn affects the conductivity and lifespan of the busway.

4. Poor Welding Process

The poor welding process of the busbar trunking system can lead to fractures at the weld joints, thereby affecting the mechanical strength and service life of the busbar trunking system.

5. Substandard tin plating

Tin plating is used to enhance the conductivity and oxidation resistance of the busbar conductor. If the tin plating layer is too thin, it can more easily lead to oxidation and corrosion on the surface of the busway, thereby affecting its overall lifespan.

6. Substituting Brass for Copper

Some manufacturers may use T3 brass instead of T1 copper or T2 copper to save production costs. However, T3 brass generally has lower purity and its resistance may not meet the conductivity requirements. This can result in poor electrical performance of the busway, increased power consumption, and even short circuits due to excessive temperature rise.

7. The casing is thin as a cicada's wing.

Some manufacturers use aluminum casings as thin as a cicada's wing for their busway systems. Such busway casing is prone to deformation, with low mechanical strength, making it susceptible to damage.

8. Poor Connection Structure

The connector has a poor connection structure, which can easily lead to loose structure, breakage, and moisture ingress at the junction of the CG BUSWAY, potentially resulting in burning of the CG BUSWAY due to short circuits. In the illustration below, the connector, once affected by moisture, corrodes the copper plate, deteriorating its conductivity and increasing power consumption.

9. Side plate without heat dissipation fins

Some manufacturers, in order to save costs, produce busway using shell side plates without heat dissipation structures, which is not conducive to the heat dissipation of the busway and can reduce its service life.

二、How to choose high-quality and practical bus ducts?
Bus ducts are main power distribution front-end trunking used instead of cables. Choosing high-quality and practical bus ducts directly impacts the safety and service life of major power distribution equipment.

CG BUSWAY reminds us that in order to correctly select bus ducts, we must pay attention to the following four points:

1. Pay attention to the conductors of the busway

When copper is used for the busway conductor, both T1 and T2 copper materials can be used, but remember not to use brass because of its poor conductivity and tendency to heat up;

Additionally, the purchased materials must be consistent inside and out, as it is crucial to avoid situations where the exterior is copper while the interior is made of aluminum or other materials;

Furthermore, we must also be cautious of excessive punching in the conductor, untreated surfaces, and other similar practices, as these are essentially cost-cutting measures employed by manufacturers.

2. Pay attention to the shell material

There are three common materials for the shell: aluminum, iron, and aluminum alloy. Some inferior manufacturers may use poor-quality aluminum plates. Would you dare to use aluminum shells that are prone to deformation?

Also, pay attention to the mechanical strength of the busway's side plate structure. If it is too soft, it is not safe.

3. Focus on Insulation Materials

When it comes to insulation materials, we prefer DuPont insulation materials or high-quality domestic brands. While price may vary, quality ensures an adequately safe CG BUSWAY.

It is preferable to have a side plate heat sink structure, which aids in dissipating the heat generated by eddy currents during the operation of the CG BUSWAY.
