For the bus bar frame option, first confirm the specification of your own copper bar. After confirmation, confirm how many phases your bus bar frame is, how many copper bars in total, and what is the phase to phase distance between each phase copper bar and another phase copper bar. Select the type according to the size you need. The common spacing is 55, 80, 100, 110, 120, 130, 140, 150, 160, 175 and 180 (unit: mm). The number of phases includes single phase, three-phase, four phase and five phase. The copper bars that can be installed in each phase are divided into single row, double row, three row and four row.There is also the size of the mounting screw hole of the busbar clamp.

ToggleCable glands, also known as cable connectors or fittings, are essential components used to secure and terminate cables in electrical installations. These devices provide strain relief and ensure a secure connection, preventing cables from being pulled out or twisted. One of the most critical features of cable glands is their ability to maintain the integrity of the cable entry point. A waterproof cable gland offers enhanced protection against water ingress, making it ideal for use in harsh environments and outdoor applications. By sealing the cable entry, it ensures that electrical systems remain safe and operational, even under challenging conditions.
Cable glands come in various specifications to meet the diverse needs of different industries. Key specifications include:
Selecting the correct cable gland size involves considering the cable diameter, thread type, and the environmental conditions where the gland will be used. The size must match the cable diameter to ensure a secure fit and proper sealing.
Cable Diameter (mm) | Gland Size (Metric) | Gland Size (PG) | Gland Size (NPT) |
---|---|---|---|
3 – 6 | M12 | PG7 | 1/4″ |
6 – 10 | M16 | PG9 | 3/8″ |
10 – 14 | M20 | PG11 | 1/2″ |
14 – 18 | M25 | PG13.5 | 3/4″ |
18 – 25 | M32 | PG16 | 1″ |
25 – 33 | M40 | PG21 | 1 1/4″ |
33 – 42 | M50 | PG29 | 1 1/2″ |
42 – 54 | M63 | PG36 | 2″ |

Heat shrink tubing is a tubular heat-sensitive plastic sleeve that shrinks in diameter when heated. It is used to insulate and protect cables, wires and hoses. Heat shrink tubing can also be used as a covering for cable connectors. When heated, the tube shrinks tightly around the connector, creating a waterproof and corrosion-resistant seal. Heat shrink tubing provides electrical insulation, mechanical protection, environmental sealing and strain relief. Our heat shrink tubing offers single and double wall tubing designed for a variety of applications including back end connector sealing, breakout and connector-to-cable transitions. It is a reliable alternative to tape, molding or potting. In addition, our shrink tubing is made of high-quality materials that provide superior protection and insulation. We offer a variety of sizes and colors so you can find the perfect heat shrink tubing for your needs.
High-voltage insulators are essential components in high-voltage applications. It is designed to protect people and equipment from high voltage electricity. For electrical building maintenance, power plants, substations and other places that require insulation. An electrical insulator is a material that hinders the free flow of electrons. Providing reliability, availability and power density is critical for all modern electrical energy and power systems.
Low voltage insulators are an essential part of any electrical system. It provides the reliable and efficient insulation needed to protect electrical equipment and circuits. It is used to protect people and equipment from injury or damage due to short circuits or overloads in electrical systems. Low-voltage insulators are made of high-quality materials and are durable. Haitan offers a full line of low voltage brackets, cost-effective insulators with extremely high electrical and mechanical parameter stability and very high leakage current resistance.
MD bus support busbar frame insulator is made of BMC / SMC, which is used to support the bus circuit system in the same equipment and to support single-phase, three-phase, four phase and five phase buses. It is used for low-voltage distribution lines and communication lines, and is widely used in electrical applications such as distribution box, switchgear, inverter and green power supply.
