Interface Brushless Battery Hydraulic Crimper 12-Ton 400mm2 GLS-400

Overcoming high-volume termination fatigue with brushless electro-hydraulic power

Within the highly demanding electrical engineering and mechanical electrical plumbing (MEP) sectors, executing hundreds of high-capacity copper and aluminum cable terminations presents a severe logistical and physical bottleneck. Utilizing traditional manual hydraulic pumps or heavy ratcheting tools for continuous, large-diameter cabling induces rapid, debilitating operator fatigue. This physical exhaustion inevitably leads to inconsistent, under-pressurized crimps. In high-voltage applications, a microscopic air gap inside a lug due to an incomplete crimp will drastically increase electrical resistance, leading to hazardous arcing, localized melting, and ultimately, catastrophic thermal failures within critical industrial switchgears.

The flagship Interface GLS-400 battery-powered hydraulic crimping tool is meticulously engineered to entirely eradicate these physical limitations. By integrating a highly advanced, maintenance-free brushless motor with a high-pressure Continuous Pressing function, this premium cordless tool delivers massive, instantaneous electromechanical compression force directly at the workface at the simple pull of a trigger. Engineered to provide all users—from independent commercial electricians pulling residential sub-mains to mega-scale industrial panel builders configuring massive regional power grids across Singapore and Malaysia—with absolute mechanical consistency, the GLS-400 ensures that every single heavy-duty termination is executed with flawless, factory-grade structural integrity.

Interface brushless battery hydraulic crimper GLS-400

120KN continuous hydraulic compression and 42mm stroke dynamics

The physical act of deforming heavy-gauge metal lugs around thick copper strands requires immense, sustained mechanical pressure. The Interface GLS-400 accomplishes this through a highly refined electro-hydraulic drive system.

• 12-Ton (120kN) cold-welding capacity: The internal hydraulic manifold of the GLS-400 is factory-calibrated to deliver a maximum compression force of 120 kN (12 tons). This specific tonnage is the strict electromechanical threshold required to process massive 400mm2 cross-sectional cables safely. When the 120kN force is applied to the hardened steel dies, it physically crushes the metallic structure of the lug, forcing the internal copper strands to deform and bind together in a process known as cold-welding. This extreme pressure completely expels all interstitial oxygen from the connection, guaranteeing a gas-tight, oxidation-proof electrical joint with maximum conductivity.

• Continuous Pressing function: Unlike primitive tools that apply force in jerky, stepped increments, the GLS-400 utilizes a highly advanced Continuous Pressing function. Once the trigger is engaged, the fluid pressure builds smoothly and relentlessly until the exact 120kN threshold is reached. At this precise moment, the internal pressure relief valve automatically trips, safely retracting the piston. This guarantees absolute uniformity across thousands of crimps.

• Extended 42mm piston stroke: To accommodate the massive physical dimensions of 400mm2 heavy-duty splices, C-taps, and long-barrel lugs, the cylinder is engineered with an extended 42mm linear stroke. This generous spatial clearance allows the operator to easily maneuver thick, rigid cables into the die block without aggressively bending or damaging the exposed copper cores prior to the compression cycle.

Brushless motor efficiency and 18V 5.0Ah power management

The defining technological leap of the Interface brushless battery hydraulic crimping tool GLS-400 "Flagship" model lies in its electromechanical power generation and energy storage systems, designed specifically for unyielding industrial endurance.

• Advanced brushless motor technology: Traditional DC power tools rely on physical carbon brushes that constantly drag against the motor commutator, generating massive thermal friction, consuming excess battery power, and eventually requiring mechanical replacement. The GLS-400 completely eliminates this vulnerability by utilizing a state-of-the-art brushless (BL) motor. By using electronic microprocessors to perfectly synchronize the magnetic fields, the motor operates with near-zero internal mechanical friction. This drastically reduces operating temperatures, significantly increases torque output, and extends the physical lifespan of the motor, supporting the tool's verified warranty rating of 30,000 operational cycles.

• High-capacity 18V 5.0Ah Lithium-ion cells: Driving a 12-ton hydraulic pump requires massive bursts of sustained electrical current. The GLS-400 is equipped with premium 18V Lithium-ion batteries featuring a high-density 5.0Ah capacity. This exceptionally large energy reservoir guarantees that a single technician can execute hundreds of maximum-capacity 400mm2 crimps on a single charge. The intelligent battery management system (BMS) prevents deep-discharge and thermal overloading, ensuring the equipment remains fully operational during brutal, all-day infrastructure deployments.

Open-pin latching head and 360-degree rotational geometry

Routing and terminating thick, unyielding 400mm2 power cables within the heavily congested confines of a commercial transformer cabinet or a subterranean electrical trench is a severe logistical challenge.

• 360-Degree rotational axis: To adapt to highly restricted spatial envelopes, the entire steel crimping head of the GLS-400 is mounted on a fully rotational 360-degree swivel joint. This allows the heavy-duty operator to securely grip the ergonomic base of the tool in a comfortable, structurally sound posture, while independently rotating the jaw assembly to perfectly match the precise angle of the incoming cable lug. This eliminates the need for the operator to aggressively twist their wrists or force heavy cables into unnatural, physically stressful angles.

• Open-pin tool head architecture: Standard closed-head (C-head) crimpers require the operator to physically thread the entire length of the heavy cable completely through the jaw opening—a physically impossible task when terminating the middle section of an existing cable run. The GLS-400 features a highly efficient open-pin (latching) mechanism. The operator simply pulls the heavy-duty retaining pin, opens the top half of the die block entirely, places the tool directly over the mid-span of the cable, and re-secures the steel pin. This architectural advantage drastically accelerates workflow for independent maintenance crews and major utility teams alike.

Standard operating procedure for heavy-duty cable termination

To guarantee strict compliance with international electrical codes and ensure maximum operator safety when handling 12-ton kinetic forces, all users must execute the following workflow:

1. Die selection and insertion: Accurately measure the cable cross-section and select the precisely matched pair of hexagonal dies from the provided 16mm2 to 400mm2 kit. Pull the retention pin, open the head, and snap the die halves securely into the upper and lower seating tracks.

2. Lug positioning: Strip the cable insulation to the exact depth of the lug barrel. Insert the exposed copper strands fully into the lug. Position the tool head over the lug and securely lock the retaining pin. Ensure the lug is perfectly centered between the dies to prevent unequal mechanical loading.

3. Electromechanical actuation: Depress and hold the trigger. The brushless motor will rapidly drive the Continuous Pressing function. Keep your hands strictly clear of the jaw assembly.

4. Auto-retraction and verification: Maintain continuous trigger pressure until the tool physically completes the cycle. The internal valve will automatically "pop" and the piston will rapidly retract. Extract the cable and visually verify that the hexagonal crimp is perfectly symmetrical, sharply defined, and free of any metallic burrs or sharp extrusions.
