Product Description

The MPP-LBS-12/24/40.5 pole-mounted load switch is widely used in medium-voltage distribution lines for both urban and rural power networks, industrial power systems, and regional power supply projects. It comes with both manual and electric operation options. Manual operation is suitable for routine maintenance and inspection.

The MPP-LBS-12/24/40.5 pole-mounted load switch For distribution lines that need remote control, the MPP-LBS can be equipped with an electric operating mechanism based on actual requirements and connected to the corresponding automation control system. This allows for remote monitoring and switching operations, so maintenance personnel don't need to go to the site frequently. They can check the line status and operate it remotely as needed, reducing on-site work and saving time and labor. For models with manual operation, the staff can handle switching and routine maintenance directly on-site.

The MPP-LBS-12/24/40.5 pole-mounted load switch can be offered in different models depending on voltage levels and installation requirements. Customers can select the right equipment based on system voltage, power supply mode, load conditions, and onsite space. Since the device operates outdoors for extended periods, factors like temperature changes, humidity, and other environmental conditions need to be considered carefully to make the right choice.

In practical engineering applications, customers must conduct a rigorous assessment and verification based on parameters such as rated voltage, rated current, and short-circuit making capacity; additionally, if remote control is required, it is necessary to confirm whether the specific model supports this function. Selecting the appropriate model with due diligence and ensuring proper installation will meet the operational requirements of medium-voltage distribution lines and help ensure the equipment's normal operation.

Product Features

01/

Wide Voltage Compatibility

Covers voltage ratings of 12kV, 24kV, and 40.5kV, supports both 50Hz and 60Hz frequencies, and complies with regional power distribution regulations.

02/

Versatile Operation Modes

Features manual operation as standard, with optional motorized mechanisms and intelligent control functions. This enables both on-site operation and remote monitoring, facilitating the automation of distribution networks.

03/

Reliable Fault Section Isolation

Capable of handling various operating conditions ranging from load currents to overload currents. In the event of a line fault, it rapidly isolates the faulty section while protecting and maintaining service to healthy sections, thereby ensuring the safe operation of the rest of the line and enhancing overall grid stability.

04/

Modular Design

Utilizes SF6 gas insulation to achieve a highly sealed structure and exceptional arc-extinguishing performance. The cable connection method simplifies installation and commissioning while reducing maintenance requirements, making it an ideal choice for the renovation and upgrading of cable networks.

05/

Superior Weather-Resistant Enclosure

Offers a choice of porcelain or organic material enclosures, both featuring excellent resistance to aging and condensation. Ideally suited for outdoor installation, it operates reliably even in harsh environments characterized by high temperatures, high humidity, and heavy dust.

06/

International Standard Compliance

Meets the diverse technical requirements of overseas projects and is widely deployed in distribution networks across Africa, the Middle East, and Southeast Asia. It is frequently utilized as pole-mounted switchgear, particularly in international EPC distribution projects.

Key Application Scenarios

Sectionalizing switches and tie switches for overhead lines in urban and rural distribution networks.

Distribution network automation upgrade projects (enabling fault location and isolation).

Outdoor distribution branch protection for industrial parks, mining sites, and residential complexes.

Overseas power EPC projects (12kV–40.5kV outdoor pole-mounted distribution equipment installations).

FAQ

Q1: What are the rated voltage and rated current specifications for the MPP-LBS load break switch?

A: This series covers three rated voltage levels - 12 kV, 24 kV, and 40.5 kV - offers rated current options of 400 A and 630 A, and supports grid frequencies of 50 Hz and 60 Hz...

Q2: Does this equipment use SF6 insulation? What are its safety and reliability characteristics?

A: The primary models utilize SF6 gas insulation, featuring mature and stable sealing technology, excellent insulation performance, rapid arc-extinguishing capabilities, and reliable current-interruption operation.
