1-2. Advantages
(1) No holes in conductors Joints are made without piercing holes of conductors. Clamping bolts do not run through the conductors in order to secure mechanical strength and electrical reliability. (2) Contact area As joints are made without piercing of conductors more contact area can be secured to recuce the resistance. (3) Joint by leaf springs A spring material wider than the bus bar is used in jointing so as to ensure a constant contact pressure, which does not cause any unbalance of temperature rise and current flow. (4) No stress concentration Providing very high reliability electrically and mechanically because of using high strength insulation spacers and removing piercing holes in the conductors which may cause stress concentration at the jointing area. (5) Ideal connection To pursue the ideal connection jointing between conducts is made at the same time with that of between ducts. (6) Ease of installation and maintenance One-touch joint system enables easy installation. Checking the jointing area is possible without any interruption of the power.

Installation manual
This manual describes the precaution that must be followed in the handing GH-P Type Bus Duct. Be sure to read it though before the work.
1-2. Preparation
1) Thoroughly check the bus duct laying route to see if there are any obstacles, eat source, water leakage, etc. Check also the dimensions of arrangement and buildings and equipment beforehand. 2) Check both the straight and curved routes of transportation from the place of storage to the laying site. 3) Install the hanging bolts or trestles for hangers beforehand. set the hanger pitch to support two places with one unit as a standard. 4) Investigate the site conditions in advance and determine the most advantageous laying order. The work usually start from connecting the bus duct to the transformer or the switchboard, but in case this impossible to determine precisely the positions of elbows T-branch, and then start construction, and other items which serve as the points of bus duct installation.
1-3. Laying
1) Use sufficiently strong materials and equipment for transportation and lifting. The weight per 1m of GH-P type bus duct is given in the catalogues. However, the special bus duct with box sometimes weight 2-3 times more than those shown in this table. 2) When hanging the bus duct with a rope, insert thick pieces of rag or corrugated card between them to prevent the bus duct from being damaged. When handing a copper conductor bus duct of over 2500A, use a piece of strong wood where the rope is applied so as to prevent the housing from being deformed. 3) Before jointing bus duct, examine whether the conductor contact surface or insulating materials are damaged. Also check that they are not soiled with dust, dirt and other foreign matter: otherwise, clean them thoroughly. 4) First, make loose joints of bus ducts over the whole run. After measuring the dimension, proceed the normal jointing. GH-P type bus duct allows dimensional adjustment of approx. 3mm, at a join. 5) In case a megger value is found abnormal after jointing of the whole route, much time is spend to detect faulty parts. It is therefore recommended that the megger checking be partially conducted even during the jointing work. 6) When the work suspended during the construction, the ends of the connecting section shall be protected against water and dust. 7) Take care not to use the installed bus duct as scaffold or material yard.
2. Jointing procedur
joint GH-P type bus ducts, as follows:
1) Confirm the male-female condition of two bus ducts to connected by arranging them face to face. 3W 4W
Be sure to check the directions of the male and female ends of the bus duct jointing section, as shown in route drawing it is described. 2) Remove the leaf springs temporarily fixed with bolts, and insert them until the bolt holes of both bus ducts almost conform with each other. 3) Fasten the bus duct with bolts, nuts and washers by soldering both sides of the jointing section between leaf springs.
Do not fail to place the washers to the nut side with the groove for rotating stop set to the head side of the bolt.
4) Tightly fasten until the leaf springs become almost flat. Do not tighten only one of the bolt first and then the other. tighten the two bolts alternately. Any type of spanner may be used.
5) Set the joint cover after ascertaining that there is no foreign matter or abormality inside the joint section. when the jointing bolts are not tightened sufficiently, the nuts (bolts) touches the joint cover and fitting will be impossible. in this case, tighten the nuts again.
2) Do not fail to face the blue surface of the Belleville washer (cup washer) towards the inner side (conductor side).

5. Earthing of housing
At the connection section of mutual bus ducts, the continuity of the earth is secured automatically by fixing the joint cover. Further, with the equipment is performed by flange connection, it will be electrically connected with the toothed lock washer attached to the bolt for the flange biting into the flange of the equipment and the bus duct when the bolt is clamped. in case the terminal is not flange connection, set the earth by connection the IV line to the stud fitted to the terminal section.

take into consideration the work schedule in advance since it takes a minimum of 2 weeks for the actual delivery of the bus duct.
(1) Check the external appearance Checking to see whether there is deformation, damage, dirt, etc. throughout the whole length of the bus duct and whether there is dislocation, bending and other abnormality of the connecting covers, hanger and plug-in appliances. (2) environmental check The environment where the bus duct is used sometimes changes after its installation. Check whether the environment has become hazardous even partially due to water, moisture, high temperature, corrosive gas, immoderate vibration, duct etc. (There will be no problem with the bus duct where countermeasures are taken from the initial stage.) (3) check the connection section There will be no problem of loosening of the connection section of GH-P type bus-duct by "concordance" as leaf springs of high deflection are employed for the connection section. Therefore, periodical increased clamping is unnecessary. However, when the contact surface is soiled or deteriorated during the construction or during the storage, a simple check by touching the external portion during the current sending is recommended as the above effects would gradually arise. (If the temperature of the connection section and the main body is about the same, there will be no problem.) (4) Check the load condition After the construction of the plug in bus duct. increase of load is expected at the early stage. carry out checking whether the total of load is not exceeding the capacity of the bus duct at the time the load is increased. Especially, pay attention when the main line is branched by T-branch or cross.
Conduct the above mentioned check about a year excluding Paragraph (4).
Fool-Proof Mechanism
Notch
Connecting cover
When clamping is insufficient, the nut will become a stopper and the connecting cover will not be able to be fitted. When clamping is adequate, the connecting cover will fit
Merits 1. Operation is simple. Clamping is only required until the spring becomes flat and special tools such as torque-wrench are wholly unnecessary. 2. Operation id safe There is absolutely no shock at the time of cutting such as torque bolts, and operation at elevated spot is also safe. 3. Reliability is great As regards the conventional torque management, it is difficult to obtain constant clamping force due to dispersion of the coefficient of fiction.
