Heavy duty connectors ensure reliable transportation performance

THE APPLICATIONS OF HEAVY DUTY CONNECTORS IN TRANSPORTATION

KEY ROLE IN THE TRANSPORTATIONS

The role of heavy duty connectors in transportation equipment such as rail transit can be summarized as "one-time insertion, comprehensive solution".

TIRE CHANGE & REPAIR

It not only pre-builds the power, control, network, air conditioning, braking and other subsystems as "plug-and-play" modules, but also provides highly reliable and highly integrated connection solutions for the two most critical systems of the train - traction power and signal control, and meets the strict requirements in extreme operating environments.

THE ADVANTAGES OF HEAVY DUTY CONNECTOR

Why are our products used across industries?

Pre-installation

Achieve pre-installation, pre-installation of large and complex circuits.Significantly improves equipment installation efficiency and reduces wiring error rates.

High integration density

Heavy duty connectors provide high-density integration connections The rich combination methods maximize the effective utilization of equipment space.

Modular structure

Heavy duty connectors conveniently and efficiently achieve modular structures for various functional modules of the equipment.

High protection level

Provides effective protection in harsh environments such as sand, rain, cold, snow, ice, and oil contamination.

THE CORE INTERFACE OF THE TRACTION POWER SYSTEM

Which is located between the traction converter and the motor, capable of carrying a large current of 200A. It adopts multiple redundant designs to provide a "double insurance" power channel for the train. The modular HM flexible combination structure reduces maintenance time by 70% and significantly improves operational efficiency. High current and low current can be freely assembled within the same connector, eliminating the need for additional wiring space.

Located between converter and motor.

Handles large 200A current efficiently.

Modular design cuts maintenance time 70%.

Flexible current assembly saves wiring space.

High-Reliability Redundant Design

Located between the traction converter and motor, it can handle high currents up to 200A. With a multi-redundant design, it provides a "dual-insurance" power channel for the train, significantly enhancing system safety.

Modularized Efficient Maintenance

Featuring an HM flexible modular structure, it allows free assembly of high/low currents within the same connector, saving wiring space. This reduces maintenance time by 70% and greatly improves operational efficiency.

PROFESSIONAL DESIGN

The HK series of inserts are divided into a power area and a signal area. The maximum current that the power area can withstand is up to 100A. The HM series of inserts can offer an option with a maximum current of 200A.

The product lineup includes the HK series with more than ten standard configurations, complemented by the HM series which features modular frame designs for highly customizable combinations tailored to specific application needs.

Intelligent operation and maintenance interface

It is equipped with an intelligent monitoring module that provides real-time feedback on connection status, and the accuracy rate of fault early warning reaches 99.5%. The color coding system enables "zero-error" rapid maintenance and further reduces downtime.

WHY CHOOSE US?

Looking to the future, heavy-duty connectors are continuously evolving in three major directions: lightweighting (reducing weight by 30%), fiber-copper cable hybrid transmission, and AIoT intelligent operation and maintenance, providing rail transit with connection solutions that offer higher safety redundancy, faster data transmission, and lower life cycle costs.

From freight locomotives to high-speed EMUs, from metro trains to engineering maintenance vehicles, heavy-duty connectors have been deeply integrated into key systems such as traction, braking, signaling, and auxiliary power supplies, becoming the "core interface units" of the electrical architecture of rail transit.

Its modular and scalable architecture not only meets the differentiated demands of multiple vehicle models and systems at present, but also reserves sufficient space for subsequent technological upgrades and functional.
