Cable Dual-Nozzle Safety Piercer

The MOEORW-WLS86 Cable Dual-Nozzle Safety Piercer (also referred to in the market as Cable Dual-Nozzle Piercer or Remote-Controlled Cable Safety Piercer) is a non-contact operating device specifically designed for safe cable piercing after cable identification. Featuring a dual-nozzle parallel structure, the device employs two triggering modes-remote control and timed delay-to maintain physical isolation between operators and high-voltage cables, fundamentally replacing the manual hammer-piercing method long used in the industry. The product is strictly developed in accordance with Article 234 of DL409-91 "Electric Power Safety Work Regulations (Power Line Section)" and is applicable for pre-verification piercing of various power cables ranging from 6kV to 35kV and below, including XLPE and oil-impregnated paper-insulated cables. Also known among users as a Power Cable Dual-Angle Piercing Device or Cable Dual-Nozzle Probe Piercer, its core value lies in replacing close-range manual operation with remote control.

During cable relocation, reconnection, or removal operations, even after the target cable has been identified using a cable identifier, there remains a risk of live-wire misjudgment on-site due to back-feeding, induced voltage, or identification errors. If manual steel rod piercing is employed and the cable is actually live, the instantaneous short-circuit current will pass directly through the human body, causing fatal injury. The MOEORW-WLS86 Cable Safety Puncture Tool utilizes a remote firing mechanism that allows operators to withdraw to a safe distance before executing the piercing action, converting the consequence of "live-wire mis-piercing" from personal injury to equipment damage-an upgrade at the level of intrinsic safety. This Remote Dual-Nozzle Cable Piercing Tester was originally designed precisely to address this long-standing safety hazard in the power industry.

1. Dual-Nozzle Synchronized Piercing – Two-Directional Piercing in One Setup

The device is equipped with two independent nail guns, capable of piercing the cable from two different angles simultaneously after installation. Industry standards require that each cable be pierced in at least two to three directions to ensure complete dissipation of residual internal charge. The dual-nozzle design allows operators to complete two-thirds of the required piercing quantity with a single clamping, significantly reducing on-site operation time-a notable efficiency advantage that distinguishes this Cable Dual-Nozzle Piercer from single-nozzle devices.

2. Non-Contact Dual Triggering Mechanisms

Remote Mode: Operators withdraw to a distance of ≥1 meter from the piercing point (remote effective range: 30 meters) and must press both the A and B buttons on the remote simultaneously to trigger firing, completely eliminating misfire caused by single-button accidental pressing.

Timed Mode: Suitable for underground utility tunnels with limited radio signal or high electromagnetic interference environments. Operators set the mode and must withdraw within 10 seconds, after which the device fires automatically with a delayed timer. Entering timed mode requires simultaneous pressing of both "Menu" and "Confirm" buttons on the controller to prevent accidental entry into countdown.

3. Physical Isolation from Power Systems – Built-in Lithium Battery Independent Power Supply

The device is powered by a built-in rechargeable lithium battery pack, independent of any on-site mains or test power sources. As a Remote-Controlled Cable Safety Piercer, even if the cable under test carries residual charge or is accidentally live, there is no electrical connection path between the device's internal circuitry and the power system, preventing induced or back-feed voltage from being conducted to the operator through power leads.

4. Human-Machine Collaborative Anti-Error – Dual Confirmation via Voice + Screen

The controller is equipped with a color LCD screen and real-voice audio announcements. Every operational step is accompanied by simultaneous visual text prompts and audible voice feedback. In outdoor bright light, high-noise environments, or when the operator's line of sight is obstructed, voice serves as a redundant backup to vision, effectively preventing operational errors caused by misreading the screen.

5. Arbitrary-Angle Mounting – Adapts to Complex Cable Arrangements

The U-shaped slot at the front of the nail gun, combined with the fixing plate and wing nuts, allows the device to be secured onto cables that are horizontal, vertical, inclined, or even inverted, enabling flexible selection of piercing points in densely packed cable trenches-a feature that gives this Power Cable Dual-Angle Piercing Device strong adaptability in field applications.

Scenario 1: Urban Distribution Network Cable Relocation and Undergrounding Projects
During urban road expansion, subway construction, or renovation of old city areas, underground cables in service must be identified, cut, and relocated. The MOEORW-WLS86 Cable Dual-Nozzle Probe Piercer is suitable for operations in narrow cable pits or shallow trenches, with its dual-nozzle design enabling rapid multi-point piercing and reducing road occupation time for construction.

Scenario 2: Cable Replacement in Power Plants and Substations
Cables in plant/substation cable basements and vertical shafts are densely arranged and often accompanied by strong magnetic field interference. In such cases, the timed triggering mode can be selected to avoid potential reliability issues of wireless signals in complex metal-structured environments, while operators withdraw to safe areas to await delayed firing-fully demonstrating the adaptability of this Remote Dual-Nozzle Cable Piercing Tester in complex electromagnetic environments.

Scenario 3: Collector Line Maintenance in Wind and Solar Farms
Collector lines in renewable energy farms are mostly direct-buried or mixed overhead installations, with maintenance windows heavily affected by weather conditions. The built-in lithium battery design eliminates the hassle of finding on-site power sources, and the 14kg total weight allows two-person teams to easily carry the device to tower foundations or between PV arrays for operation. As a portable Cable Safety Puncture Tool, its advantages in field environments without power sources are particularly prominent.

Scenario 4: Factory Inspection and Sampling Destructive Testing for Cable Manufacturers
Cable manufacturers must sample and pierce finished products before shipment to check insulation thickness or structural integrity. This Cable Dual-Nozzle Piercer can be fixed onto test benches to achieve standardized, repeatable piercing operations, avoiding irregular sample cuts caused by manual hammering that could affect testing accuracy.

Scenario 5: Railway Signal Cables and Trackside Power Cable Maintenance
Cables along railway lines involve critical functions such as signal control and switch power supply, with extremely short maintenance "sky windows." The device's rapid clamping and dual-nozzle synchronized piercing effectively compress operation time, ensuring completion of the required number of piercing verifications within limited sky windows-a scenario where the value of this Power Cable Dual-Angle Piercing Device is fully demonstrated.

Core Component Processing Technology: The barrel and piston rod are made of 40Cr alloy steel through quenching and tempering treatment and precision grinding, with an inner bore roughness of Ra0.8μm, ensuring smooth movement of the piston rod under frequent impact and resistance to scoring and seizing.
