I. use range and location
1. It is commonly used in user engineering in the province. In principle, it is used in my company's user engineering including the European change.
2. The proposal for the provincial and foreign projects is widely used in the europe-wide area and is decided by the group leadership.
3. The current of the 1080 aluminum busbar is in 1300A and below.The corresponding 1080 aluminum busbar specifications are LMY100 x 10 and below.
4. The user's distribution room project: the main female platoon (including the zero row and grounding row), all require that the material of the order system drawing be retained, and the copper row should be used in the part of the outlet cable. The range of aluminum can be used: the GGD type low voltage cabinet;XGN, HXGN high pressure cabinet all;The incoming line, contact and capacitor cabinet of drawer type low pressure cabinet are all used.Specifically by design.The drawing line of the system design drawing and the use of 1080 aluminum busbars of the copper bus (TMY) are not marked.
5. European project: use copper platoon in the part of the outlet cable.Consider the switch cabinet, main bus line (excluding zero row and grounding row), transformer to low pressure cabinet all use aluminum busbar.
6, Technical design production figure should be used in the system diagram to determine requirements: lead the busbar, branch bus material specifications, the production department should be carried out in accordance with the corresponding construction, ensure the use of 1080 aluminum busbar replacement.
7. Requirements for 1080 aluminum busbar : supply department should choose high-quality electrical aluminium busbar to ensure the quality of use.
Requirements:
1. the national standard lap joint, busbar and busbar busbar and branch line, busbar and electrical terminals lap, the lap surface must level off, clean and coated with electricity compound (conductive paste), and meet the following requirements.
A : Copper and copper: outside, high temperature and damp or corrosive gas inside the bus, must be tin tin.The drying chamber can be directly connected.
B : aluminum and aluminum: direct connection.
C : copper and aluminum: in dry room, copper bus tin;When outdoor or air relative humidity is close to 100% indoor, copper aluminium transition board should be used, copper end should be tin tin.
D : steel and copper or aluminum: the steel lap joint must be tin.
2. Bus connection: the contact surface of the aluminum busbar shall be tightly connected, and the connecting bolt shall be fastened with torque wrench.
