Zupper Battery Hydraulic Crimping Tool 240mm2 SL-240

Overcoming confined switchgear limitations with inline electromechanical architecture

Within the highly congested environments of commercial electrical engineering, panel building, and mechanical electrical plumbing (MEP), technicians frequently encounter severe spatial restrictions. Routing and terminating heavy-gauge copper cables inside densely packed distribution boards, narrow control cabinets, or elevated cable trays makes utilizing standard pistol-grip hydraulic crimpers physically impossible. The bulky perpendicular motor housings of traditional tools simply cannot fit between tight busbar arrays, leading to improper die alignment, operator fatigue, and structurally compromised electrical joints.

The Zupper SL-240 battery-powered hydraulic crimping tool is meticulously engineered to bypass these spatial limitations through a specialized inline (stick-type) electromechanical architecture. By aligning the drive motor, the hydraulic pumping mechanism, and the crimping head on a single, streamlined vertical axis, the SL-240 eliminates the bulky side profile entirely. Engineered for independent electricians and commercial panel builders across Singapore and Malaysia, this highly maneuverable 50kN platform allows operators to effortlessly slide the tool into the narrowest switchgear cavities and execute flawless, high-capacity terminations with absolute one-handed control.

Zupper battery hydraulic crimping tool SL-240

50KN cold-welding capacity and 14mm stroke dynamics

Despite its miniaturized footprint, the physical act of deforming industrial metal lugs still requires immense, sustained mechanical pressure. The Zupper SL-240 accomplishes this via a highly optimized micro-hydraulic drive system.

• 50kN (5-Ton) electromechanical compression: The internal hydraulic manifold of the SL-240 is factory-calibrated to deliver a maximum compression force of 50 kN. This targeted tonnage is the strict mechanical threshold required to physically crush 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 expels all interstitial oxygen from the connection, guaranteeing a gas-tight, oxidation-proof electrical joint with maximum conductivity.

• Dual-material crimping range: The 50kN force output is precisely calibrated to process copper (Cu) cables up to a maximum cross-section of 240mm2. Due to the inherently different metallurgical expansion properties and structural densities of aluminum, the machine is rated for a maximum aluminum (Al) capacity of 185mm2.

• 14mm piston stroke: To maintain the tool's ultra-compact profile while providing adequate spatial clearance for standard lugs, the cylinder is engineered with a strict 14mm linear stroke. This highly efficient stroke length minimizes the hydraulic fluid travel distance, resulting in rapid cycle times for high-volume repetitive terminations.

3.0kg ultra-lightweight profile and 18V power management

The defining operational advantage of the Zupper SL-240 lies in its exceptional power-to-weight ratio, designed specifically for unyielding continuous mobility.

• 3.0kg one-handed deployment: The most transformative aspect of the SL-240 is its equipment net weight of strictly 3.0 kgs. This ultra-lightweight engineering, combined with the ergonomic inline grip, shifts the tool's center of gravity directly into the operator's palm. This allows a single technician to easily hold the cable in one hand and execute the crimp with the other, eliminating the need for a secondary assistant and drastically reducing musculoskeletal fatigue during overhead line work.

• 18V 2.0Ah rapid-charge energy system: To maintain the extreme lightweight profile, the SL-240 is equipped with compact 18V Lithium-ion batteries featuring a highly efficient 2.0Ah capacity. While lighter than massive 5.0Ah bricks, these cells deliver high-discharge currents to drive the 50kN pump rapidly. To ensure zero operational downtime on the job site, the standard package includes two battery packs and a rapid charger capable of replenishing a depleted cell in approximately 40 minutes.

Standard operating procedure for inline cable termination

To guarantee strict compliance with international electrical codes and ensure flawless structural integrity, all operators utilizing the SL-240 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 10mm2 to 240mm2 kit. Snap the die halves securely into the upper and lower seating tracks of the jaw assembly.

2. Lug positioning and horizontal alignment: 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. The operator must ensure the copper cable and lug are placed strictly horizontally within the jaw assembly. Angled or vertical deviations will result in uneven die convergence, damaging the tooling and severely compromising the structural integrity of the cold-weld.

3. Electromechanical actuation and verification: Depress the trigger to activate the 50kN hydraulic pump. Due to the enclosed electromechanical architecture and strict mechanical cold-welding physics, this compression process is entirely arc-free. Sparking absolutely does not occur during the termination cycle, guaranteeing operational safety even within sensitive industrial environments.

4. Auto-retraction: Maintain continuous trigger pressure until the tool physically completes the cycle. The internal valve will automatically release upon reaching 50kN, and the piston will rapidly retract, allowing for immediate tool extraction.

Technical specifications

All electrical contractors and corporate grid procurement divisions must verify absolute compatibility with the following electromechanical parameters prior to site deployment:

Premium equipment upgrade: Interface GLS-300 for 300mm2 commercial mains

While the Zupper SL-240 delivers exceptional maneuverability and lightweight performance for restricted switchgear terminations up to 240mm2, major industrial infrastructure projects frequently demand larger cable capacities. If your structural engineering requirements involve the continuous processing of thicker commercial sub-mains or underground utility lines, we highly recommend an operational upgrade to the Interface GLS-300 battery-powered hydraulic crimping tool.

Operating on a robust, highly balanced pistol-grip architecture, the Interface brushless battery hydraulic crimping tool GLS-300 represents a strategic leap in electromechanical cold-welding capability. Engineered specifically to effortlessly process heavy 300mm2 copper cables, this premium tier platform provides industrial fleets with enhanced kinetic force and unyielding continuous-duty reliability. Equipping your commercial electrical division with both the SL-240 (for rapid, confined-space panel work) and the Interface GLS-300 guarantees absolute operational readiness across any complex grid deployment.
