Product Overview

The CATU MT-9804-P Earthing and Short-Circuiting Kit is a critical life-saving safety system designed for Medium Voltage (MV / HTA) electrical substations and bare overhead lines. Manufactured by CATU (a Sicame Group brand), this equipment provides a mechanical, highly visible means of grounding and short-circuiting an electrical installation after it has been de-energized. This ensures that if the system is accidentally re-energized, or if dangerous induced voltages build up, the current is immediately directed to the ground, triggering the substation's breaker safety systems and protecting the maintenance technicians.

Engineered to strictly comply with the IEC 61230 international standard for portable earthing equipment, the MT-9804-P features an interconnected array of extra-flexible copper cables and heavy-duty phase clamps. The "P" designation in the SKU indicates that this complete set is housed in a heavy-duty, impact-resistant plastic carrying case, replacing older metal cases for better mobility and corrosion resistance in the field.

Key Features

• 10 kA Short-Circuit Rating: Built to withstand massive electrical faults, the robust copper cables and clamp junctions are rated to safely carry a short-circuit current (Icc) of 10 kA for a full duration of 1 second.

• IEC 61230 Compliant: Fully certified to meet the rigorous international standards for portable equipment used for earthing or earthing and short-circuiting, guaranteeing reliable performance during catastrophic fault events.

• Clear Silicone Sheathing: The high-grade, 40mm² multi-stranded copper cables are jacketed in a transparent silicone (or PVC) sheath. This allows technicians to visually inspect the copper strands for breakage or thermal damage prior to every use, while remaining flexible in extreme temperatures (-40°C to +70°C).

• Complete Trifurcation Assembly: The system features three-phase connection cables joined at a central trifurcation connector, which is then connected to a single heavy-duty earthing cable.

• Heavy-Duty Plastic Case: Arrives in a rugged, custom-fitted plastic transit case that protects the clamps from impact damage, keeps the copper cables free from moisture and dirt, and makes transport across rough substation terrain easy.

Technical Specifications

Ideal Use Cases & Applications

• Substation Maintenance: The mandatory safety procedure for linemen and electrical technicians working on de-energized medium-voltage transformers, switchgear, and busbars inside a substation enclosure.

• Bare Overhead Lines: Essential for shorting and grounding bare MV distribution lines during pole replacement, line repair, or insulator maintenance.

• Industrial High-Voltage Facilities: Used by dedicated electrical maintenance teams in heavy manufacturing plants that operate their own internal medium-voltage electrical grids.

Common Questions (FAQs)

Q: Why is the cable jacket transparent?
A: The transparent silicone sheathing is a critical safety feature. It allows the operator to visually inspect the inner copper strands before deployment. If the strands are broken, frayed, or show signs of previous thermal stress (melting/blackening), the equipment's short-circuit rating is compromised, and the cables must be replaced immediately.

Q: What does the "Icc 10 kA/1s" rating mean?
A: This indicates the maximum fault current the assembly can safely carry to ground without melting or mechanically failing. In this case, it can handle 10,000 amps of fault current for a duration of 1 second, giving the upstream relays and breakers enough time to trip and cut the power.

Q: Is this kit used on live lines?
A: No. Earthing and short-circuiting equipment is strictly applied after the line has been properly locked out, tagged out, and verified as de-energized using a voltage detector. It acts as a secondary safety net against accidental re-energization, not a tool for live-line work.
