I. Applicability Scope

The LSMM series dense insulation busway is suitable for power distribution systems with rated voltages below 690V, rated working currents of 100～5000A, and frequencies of 50—60Hz.

Section II: Structural Performance

1. Utilizing a rational "sandwich" phase line closely overlapped structure design, the busbar channel features a more compact shape and reduced volume, enhancing the dynamic thermal stability of the busbar system. This results in low impedance and reduced voltage, effectively preventing the formation of "chimney effect" in busbar channels during fires. Suitable for large-span installations at construction sites.

2. The housing is composed of a blend of die-cast electrical aluminum profiles and cold-drawn thin steel profiles (or it can also use a reinforced full aluminum alloy profile structure). This set of housing is lightweight, fully enclosed, and non-ventilated, featuring both the high strength of steel housings and the excellent anti-corrosion, heat dissipation, and grounding properties of aluminum housings. The special weakly magnetic aluminum side panels can reduce the eddy current phenomenon between the large current busbars, lower the heating phenomenon caused by eddy currents in the busbar conductors, and significantly enhance the current-carrying capacity of the busbars. It also forms an integral grounding system within the housing, which can effectively alleviate the pressure on the busbar PE grounding bars during large capacity grounding faults. This is accomplished in the form of a dual-safety grounding system, protecting the safe operation of the entire busway system.

3. Standardly equipped with a single-arm locking shock absorber connector, offering reliable and convenient connection.

4. The power feed socket can be conveniently set on both top and bottom surfaces without reducing its bending strength. The safety protection level of the power feed socket reaches IP54 (compliant with standard IEC529). Each socket set is equipped with a custom-designed locking mechanism that prevents dirt, dust, and incorrect operation, made of ABS engineering plastic.

3. Equipped with a standard single-arm locking shock absorber connector for reliable and convenient connection.

4. The power supply interfaces can be conveniently set on both top and bottom surfaces without reducing their bending strength. The safety protection level of the power supply interfaces reaches IP54 (compliant with standard IEC529). Each set of interfaces is equipped with a custom-made locking mechanism to prevent dirt, dust, and incorrect operation, made of ABS engineering plastic.

Section 3: Insulation Configuration

1. The LSMM series busway insulation medium primarily uses insulating material polyester film (DuPont Mylar), which boasts excellent high-temperature resistance (no toxic gases emitted at high temperatures), high dielectric properties, and an insulation grade of "B". Alternatively, the insulating material "Plastic King" - tetrafluoroethylene定向 film (SFM-3) can be used, with a high temperature resistance level (-1800C to +2500C), single-layer voltage withstand capability of 6000V, and an insulation grade of "C". It has an insulation aging life of over 50 years and is a performance product among current practical insulating materials.

IV. Main Technical Parameters

1. Features a "sandwich" seal structure design, with general protection ratings of IP42, IP54, and can reach IP65 upon special requests.

2. The busbar system can withstand a working frequency voltage of 3750V, with no puncture or flashover phenomena for a duration of 1min.

3. The busbar system, when operating at the rated current for a long period, its temperature rise does not exceed: at the connection terminals: 60K, on the metal housing: 30K, on the surface of the insulating parts in the slot: 40K.

V. System Components

1. Linear Segment Unit

The dense insulation busbar trunking shell structure is completely sealed, with a high protection level up to IP65, suitable for use under harsh conditions. The system selects the entire housing with a capacity greater than 50% of the phase wire as the grounding system, ensuring sufficient safety. It provides a reliable grounding path for grounding faults and a short path for ground wire short circuits. In the event of a high-capacity grounding fault, it can effectively ground and protect the entire system. The feeding busway can be installed vertically or horizontally.

The busway system can be vertically or horizontally installed, with flexible socket placements. Double-sided sockets can be set, with a small spacing of 575mm between sockets. Users can reserve sockets according to specific situations, ensuring that the busway units can still accommodate load changes or additions in the future, providing a safe, reliable, and convenient power supply environment for users.
