Overview

DHH single pole sliding contact wire, safety sliding contact wire is used to supply power to moving equipment, consisting of two parts: sliding wire guide rail (fixed part, connected to the power supply, and the normal guide rail is connected by a single length of 4m/piece or 6m/piece), collector (sliding part, can slide on or inside the sliding wire track and contact with the copper strip for power supply, collector is used to connect with the mobile motor).

Product Details

1、 Product Structure: The sliding contact wire is composed of guide rails, sheaths, collectors, hangers, connectors, fixing clips, end caps, etc. It can also be equipped with expansion sections (thermal compensation devices), maintenance sections (isolators), etc. according to user requirements.

2、 Guide rail and sheath: The guide rail is made of aluminum alloy profiles with good conductivity and strong environmental adaptability (grade 6063, status T5). The lower part of the guide rail is embedded with a "V" - shaped stainless steel groove to ensure wear resistance, stability, and good contact of the collector brush when sliding along the groove. The guide rail is generally fixed to a length of 6 meters. The sheath is composed of engineering plastics with toughness, abrasion resistance, anti-aging and flame retardancy, which has a good insulation protection effect on the guide rail and ensures personal safety.

3、 Collector: The collector is a supporting structure and is the main component that supplies power to mobile devices. Composed of specially designed carbon brushes, terminal posts or terminals, plastic covers, support arms, etc. Apply appropriate contact pressure, slide smoothly along the guide rail, and supply power to the equipment. When the equipment needs maintenance, the carbon brush of the collector can be pulled away from the guide rail to cut off the power, ensuring safety and facilitating operation.

4、 Connector (also serving as a power supply): The connector is the end connection between guide rails, reliably connected by pressure plates and bolts, and the housing is made of engineering plastic as a protective cover. A protective cover that also serves as a power supply, with a port for introducing power supply lines, and is fastened together with the connector pressure plate and bolts.

5、 Hanger, fixator, and end cover: Hanger is a component used for lifting and fixing sliding contact wire guide rails. A fixator is a device that limits the guide rail to the bracket. When the guide rail expands or contracts due to temperature changes, it guides it to extend towards both sides of the fixator. The end caps are installed at both ends of the guide rail to provide insulation and protection. The hanger and end cap are both made of engineering plastic.

6、 Expansion section (thermal compensation device): Expansion section, also known as expansion joint, thermal compensation device, etc., is composed of connector pressure plate, aluminum or copper plate for compensating power supply, lead wire, etc. The shell is made of engineering plastic. When the guide rail expands or contracts due to temperature changes, the gap is adjusted by the expansion joint to avoid deformation of the guide rail. Generally, when the length of the workshop exceeds 200 meters, a set is configured for every additional 100 meters.

7、 Maintenance section (isolator): The maintenance section is made of connector pressure plates and high-strength insulation materials, and is protected by an engineering plastic shell. According to user needs, it is mainly convenient for maintenance and use of sliding contact lines, mobile devices, etc.
