E-BD type insulated Bus duct

Freedom of trunk lines
Dramatically improved Bus duct

The Bus duct connection has no directionality, making installation easy, and the connection has a load branching function that allows for flexible response to increases and relocations of power loads.
The rated current ranges from 600A to 6000A, making this our main Bus duct product highly versatile and suitable for a variety of uses.

Product Features

PRODUCT FEATURES

POINT 01Load branch from the connection

By adding the load branching function of Bus Duct to the connection part, it is possible to flexibly respond to sudden increases or relocations of load, and the total cost can also be reduced.
POINT 02Wiring space saving

Bus ducts can be used to wire large volumes of power in one go, so they require less space than cables. Simplified wiring also allows for more efficient system management.
The minimum spacing between Bus ducts is 180 mm for the 3-wire system and 200 mm for the 4-wire system, allowing for compact installation.
POINT 03Workability tailored to the process

Bus ducts can be prefabricated and can be constructed according to construction schedules. Vertical trunk lines can be constructed for each floor according to the construction schedule, while horizontal trunk lines can be constructed for each area, which allows for the distribution of workers and shortening of construction time.
POINT 04Ideal for BCP

Bus ducts have excellent earthquake resistance, making them easy to implement in business continuity plans (BCPs), and are also used to supply power from generators that operate in emergencies. Simply plugging in a plug-in branch box allows for power to be supplied to areas where electricity is needed in an emergency, allowing for flexible response in the event of an emergency.
POINT 05Secure connection

The "Perfect Bolt" used in the connections of Bus Duct is equipped with mechanisms to perfectly manage and maintain the performance of the connection bolt, including a tightening confirmation function and a locking mechanism to prevent loosening. It protects the safety of the connection from construction to maintenance, and is maintenance-free with no need for retightening.

POINT 06Total cost reduction

Bus ducts are prefabricated, which reduces construction costs. Furthermore, by supplying power to multiple trunk lines at once, high demand rates can be applied, allowing for efficient trunk line design that matches the output of the transformer, reducing initial costs. Furthermore, the ease of load branching also reduces running costs when increasing or relocating loads.
POINT 07Stylish exterior design

Bus duct allows for a neat and tidy wiring system, and a clean appearance. In addition, the case made of Galvalume steel sheet has a stylish silver-white appearance that matches the design of modern architecture.

Galvalume steel sheet finish

GALVALUME STEEL PLATE

The Bus duct case is made of Galvalume steel sheet as standard.

*	Custom colors are available as an option. Even in the case of a custom color, the joiner side panels and aluminum parts will be the standard color.
*	Please contact us separately regarding whisker specifications.

1. Excellent durability

Due to its sacrificial anti-corrosion properties, it has 3 to 6 times the durability of ordinary zinc-plated steel sheets.

2. Flexible delivery schedule

Since the case is made from Galvalume steel sheet, there is no need for a painting process, allowing for flexible delivery schedules.In addition, since no paint is used, it is an environmentally friendly steel sheet.

3. Excellent heat reflectivity

This steel sheet has a heat reflectivity of 70-75%, which is higher than that of regular zinc-plated steel sheet (approximately 30-40%).

4. It has a beautiful appearance

The surface of Galvalume steel sheet has a silvery-white fine spangle pattern, giving it an attractive surface appearance.

5. Whisker Prevention

Since we do not use electrolytic zinc-plated steel sheets, which can cause whiskers, we can also handle projects where whisker countermeasures are considered.

Characteristics of Galvalume steel sheet

Figure 1: Sacrificial corrosion protection effect of Galvalume steel sheet

Galvalume steel sheet is an aluminum-zinc alloy plated steel sheet that combines the corrosion resistance of aluminum's passivation film with the sacrificial corrosion protection of zinc, resulting in excellent long-term durability.

特性

The surface of Galvalume steel sheet is covered with areas with a high aluminum content, on which a chemically stable and dense aluminum oxide film is formed. Under normal circumstances, this film acts as a protective film and prevents the base material from rusting. If defects (pinholes, scratches, etc.) occur in the plating layer, the aluminum oxide film and the sacrificial corrosion protection action of zinc prevent rust from progressing into the base material.

	CV Cable	E-BD type Bus duct

Outline	Uses copper conductors. It is insulated with cross-linked polyethylene. Capacity Max 600A (325mm2)	Uses aluminum or copper conductors. It is insulated with polyester sheeting. It is covered with steel plates. Capacity max 6000A
Benefits	The product body is flexible and highly earthquake-resistant. There are no restrictions on where it can be used, unlike Bus ducts. In stock, so immediate delivery is possible.	Because it is covered with steel plates, it does not become a fire spread route, and there is no generation of dioxins. There is also little leakage of magnetic flux. Since it is an assembly type, partial construction is possible. It is easy to increase or relocate the load.
Drawbacks	Some materials produce dioxins and other substances when burned or incinerated. The construction work is carried out all at once, making partial construction difficult. It has no electromagnetic shielding effect by itself. When load is increased or relocated, a new trunk line must be laid.	As this is made to order, there is no stock. There are restrictions on where it can be used (there are outdoor and indoor types). The cable itself is not as flexible as the cable itself (it is flexible enough compared to the building, so earthquake resistance is not an issue). On-site processing is not possible.
