Tram trolley wire, also known as power supply trolley device, is mainly used to supply power to moving equipment (such as trams, electric hoists, cranes, etc.). Its structure and function can be summarized in detail as follows:

structure

The tram trolley line is mainly composed of the following key components:

Jacket:

Description: The sheath is a semi-enclosed guide tubular part that serves as the main part of the conductor line.

Function: 3-16 naked guide rails can be embedded as power supply wires as needed, and each guide rail is insulated from each other to ensure the safety of power supply. At the same time, it can effectively prevent the maintenance personnel from being electrocuted during live maintenance.

Features: The length of the conduit produced by the manufacturer is different, and it can be connected to any required length, and the ordinary conduit is mostly straight, and it can also be made into an arc according to special needs.

Conductor:

Material: The main material is copper.

Specifications: According to its cross-sectional area, there are commonly used specifications of 10 square meters, 16 square meters, 25 square meters, etc.

Function: As a conductive body, it is responsible for transmitting electrical energy.

Current Collector:

Description: The current collector is a set of brush shell frames running in the conduit, driven by a fork (or traction chain, etc.) placed on the electrical mechanism (such as tram, electric hoist, etc.).

Function: Synchronous operation with the power mechanism, transmit electric energy to the motor or other control elements through the guide rail and brush. The number of poles of the current collector brush is 3-16 poles, which corresponds to the number of poles of the guide rail in the conduit.

Safety Performance:

The conductor wire shell is made of engineering plastics with high insulation performance, and the protection level can reach IP13 and IP55 levels, which can protect against rain, snow, ice attacks and hanging objects.

The transmission rails and current collectors are designed with good insulation and protection measures to ensure the safety of power supply.

Reliability:

The transmission guide rail has good conductivity, fast heat dissipation, high current density, low impedance value and small line loss.

The brush is made of metallic graphite material with high conductivity and high wear resistance, and the current collector moves flexibly and has good orientation performance, which effectively controls the contact arc and arc phenomenon.

Economical:

The power supply conductor device has a simple structure, and uses a copper bar with high current density, low resistivity and low voltage loss as the conductive body, which can save about 6% of electricity.

The design is novel, no other insulation structure is required, no compensation line is required, easy to install, saving installation materials and costs.

Convenience:

The power supply conductor unit combines multiple bus bars in a single conduit for easy assembly.

Fixing brackets, connecting clips, suspension devices, etc. are all universal parts, which are very convenient for assembly, disassembly, adjustment and maintenance.

Application scenarios

Tram trolley line devices are widely used in electric hoists, electric beam and electric single girder overhead cranes; Stackers, automatic detection lines for mechanical and electrical products, automated production lines, mobile power tools and other mobile power receiving equipment, as well as fixed laying bus ducts in factories and mines, workshops, and office spaces.

To sum up, the tram conductor line provides a safe, reliable, economical and convenient power supply solution for mobile equipment through its unique structure and functional design.
