Description

4PP320.1043-31 Motor Cable Product Description

Product Overview

Basic Information

Manufactured in strict accordance with IEC international standards and B&R global quality specifications, this motor cable complies with DIN VDE and EN industrial cable norms, and has passed full-item performance tests and aging verification before delivery. The conductor is made of ultra-fine stranded bare copper wires that meet IEC 60228 Class 6 standards, featuring high flexibility and tensile strength to withstand millions of repeated bends without breakage. The core insulation adopts high-performance polymer material with excellent dielectric strength and heat resistance, effectively isolating electric leakage and ensuring stable electrical performance under long-term load operation. Cores are identified by black insulation with continuous white numerical markings, matched with a dedicated yellow-green grounding core for clear and safe wiring in line with EN 50334 color coding standards.

The cable is equipped with a multi-layer shielding structure. A tinned copper braided shield with a coverage rate of over 85% is applied above the inner sheath, which can effectively block external electromagnetic interference and prevent internal signal leakage, fully meeting EMC requirements for industrial sites. The outer sheath is made of high-quality PUR thermoplastic polyurethane, characterized by wear resistance, oil resistance, hydrolysis resistance and low-temperature flexibility. The sheath color adopts standard industrial orange (RAL 2003) for easy identification during on-site maintenance.

In terms of electrical specifications, the cable has a rated voltage of 0.6/1 kV and a withstand test voltage of 4000 V between conductors and shield, ensuring safe operation under normal industrial voltage levels. The standard product is supplied in fixed lengths with pre-assembled industrial-grade connectors at both ends, supporting quick plug-and-play connection. Each finished cable undergoes conductor continuity testing, insulation resistance testing and shielding performance testing. The standard package contains one complete motor cable. Matching connectors, fixing clamps and cable glands need to be purchased separately. The cable has a lightweight overall structure and is easy to carry, lay and route inside control cabinets and equipment frames.

Function and Positioning

Positioned as a high-reliability hybrid motor connection cable for medium-duty industrial automation, the 4PP320.1043-31 integrates power transmission and signal transmission functions, and is mainly used to connect B&R servo motors, servo drives and corresponding control terminals in automation systems. It can work as a dedicated power and signal link for standalone automated equipment, and can also be deployed in distributed multi-axis control systems to realize stable interconnection between multiple motors and controllers.

In terms of power transmission function, the multi-core power conductors can stably transmit rated operating current for servo motors, with low conductor resistance and small power loss. The excellent heat dissipation and insulation performance allow the cable to maintain a stable working temperature even under full-load and long-term operation, avoiding safety hazards such as overheating and insulation aging. The built-in grounding core provides reliable grounding protection for the motor and equipment shell, effectively preventing electric shock risks caused by leakage current.

In terms of signal transmission function, the dedicated signal cores are designed for motor encoder signals and control signals. With the protection of the integral shielding layer, the signal transmission remains stable and free of distortion even in environments with strong electromagnetic interference such as frequency converters and high-power equipment. It supports real-time feedback of motor operating status, speed and position signals, ensuring precise closed-loop control of the servo system.

In terms of mechanical adaptation, the cable is optimized for dynamic working conditions. The highly flexible conductor and bending-resistant structural design enable it to adapt to reciprocating movement in cable drag chains, swing and rotation of mechanical arms, and other motion scenarios. It also supports fixed laying along equipment frames, inside cable trenches and control cabinets, with flexible installation methods to meet different on-site layout requirements. The wear-resistant outer sheath can resist friction from mechanical parts and scratches during laying, extending the overall service life. This cable is compatible with new automation projects and can also be used as a replacement part for maintenance and renovation of old production lines.

Core Performance Parameters

For electrical performance, the rated operating voltage is 0.6/1 kV. The insulation resistance at 20℃ is no less than 200 MΩ·km, and the withstand voltage test between conductors and shield is 4000 V without breakdown. The conductor adopts Class 6 ultra-fine stranded copper, with low internal resistance and strong current carrying capacity, which can match the rated current of supporting servo motors. The shielding layer provides excellent electromagnetic compatibility and suppresses both conducted and radiated interference.

For mechanical performance, the cable has outstanding flexibility and bending resistance. The minimum bending radius is 4 times the cable outer diameter for fixed installation, and 10 times the outer diameter for dynamic movement in drag chains. It can withstand more than 3 million reciprocating bending cycles, and the maximum moving speed can reach 300 m/min, adapting to high-frequency dynamic operation. The tensile strength and tear resistance of the sheath and insulation meet industrial heavy-duty standards, resisting mechanical extrusion and friction.

For environmental adaptability, the operating temperature range is from -5℃ to +70℃ for dynamic movement, and from -40℃ to +80℃ for fixed laying. It features excellent oil resistance and can resist mineral oil, synthetic oil and water-based coolant corrosion in workshop environments, complying with DIN EN 60811-404 oil resistance standards. It also has good resistance to moisture, mold and weak chemical corrosion, and can operate reliably in humid workshop environments. The flame retardant performance meets IEC 60332-1-2 standards, reducing fire risks in case of accidental ignition.

General Matching Accessories

Dedicated cable fixing clamps, cable brackets and routing clips are standard matching accessories, which can firmly fix the cable along equipment frames, inside drag chains and cabinets to prevent displacement and excessive tension caused by equipment vibration and movement. Professional cable cutters and stripping tools are recommended for on-site cutting and terminal processing to avoid damaging conductors and shielding layers.

Sealed cable glands and waterproof connectors are essential accessories for cable entry and exit positions of equipment and control cabinets. They can enhance the sealing performance of the cable interface, prevent dust, moisture and oil from entering the equipment interior, and further improve the protection level of the whole system. Shielded transition joints are available for extending cable length on site. All connecting accessories adopt the same shielding specification as the cable to ensure the continuity of the shielding effect.

Heat-shrinkable tubing and insulating tape are used for insulation and sealing of cable joint positions. It is recommended to use original supporting materials to ensure insulation and sealing quality. Spare cables of the same model are advised to be stored in a dry, cool and dust-free warehouse for emergency replacement during equipment maintenance. All supporting accessories comply with B&R unified industrial standards, with stable quality and complete specifications.
