The Z20 Cable Safety Piercer safely verifies zero voltage on cables up to 125 mm diameter before excavation — protecting crews from energized cables — factory direct at $2,800.
What Is the Z20 Cable Safety Piercer?
The Z20 is a field safety tool that pierces a cable sheath to verify it is de-energized before excavation or cutting. It uses a double-gun, double-angle design for two punctures in one operation. Built-in voltage detection and grounding discharge confirm zero voltage safely.
Why Must Cables Be Pierced Before Excavation?
De-energized cables can still hold induced or residual voltage from parallel circuits. Piercing with a grounded tool proves zero voltage and discharges any stored energy. This is a standard safety step for utilities, contractors, and mining operations working near live infrastructure.
What Are the Z20's Key Specifications?
The Z20 operates with wireless remote control at distances up to 20 m, with timing and remote modes and double-button confirmation. It applies to power cables up to 125 mm diameter. Dry battery power makes it suitable for field work without mains electricity.
How Does the Z20 Protect Field Crews?
A false assumption of a de-energized cable causes fatal accidents every year in cable work. The Z20's real human voice prompts synchronized with LCD display confirm the zero-voltage state audibly and visually. Complete isolation of the puncturing device from the power system adds a second safety layer.

Applicable Scenarios
- Pre-excavation zero-voltage verification — prove de-energized before digging
- Induced voltage discharge — safely discharge residual voltage from parallel cables
- Cable identification confirmation — pair with identifiers before working
- Emergency repair safety — verify before cutting after outages
- Contractor compliance — meet utility safety regulations
Testing Method
- Set up grounding — connect to a verified earth point
- Position the piercer — place perpendicular to the cable
- Advance the probe — operate the ratchet/hydraulic to pierce the sheath
- Monitor voltage — zero reading confirms de-energized status
- Hold & confirm — maintain the pierce for a few seconds
- Discharge residual — allow induced charge to drain through grounding
- Authorize excavation — proceed only after stable zero reading
Quality & Delivery
- 100% factory tested — test certificate included
- CE certified — EU compliance
- Export packaging — foam-lined transit case
- Lead time — 10–15 days
- After-sales — 1-year warranty, lifetime maintenance, free training
FAQ
What is a cable safety piercer used for?
It safely pierces a cable sheath to verify zero voltage before excavation, preventing accidental contact with energized cables.
What cable sizes can the Z20 handle?
The Z20 applies to all power cables with a diameter up to 125 mm.
Can the Z20 be operated remotely?
Yes — wireless remote control works at distances up to 20 m with double-button confirmation.
Why pierce a cable that appears de-energized?
Cables can hold induced or residual voltage from parallel circuits — piercing proves the safe state before work.
What is the Z20's price?
$2,800 with a 1-year warranty and lifetime maintenance support.
