Nastavení a příprava

Příprava pracovního prostoru

• Ujistěte se, že pracovní prostor je čistý, suchý a dobře osvětlený.
• Verify that the cable to be terminated is de-energized and properly grounded.
• Gather all necessary tools, including cable strippers, crimpers, cleaning solvents, and measuring tape.

Příprava kabelu

1. Measure and cut the cable to the required length, ensuring sufficient slack for termination.
2. Remove the outer jacket of the cable according to the specific dimensions provided in the kit's detailed instructions (refer to the included manual for precise measurements).
3. Prepare the cable insulation and conductor as per standard electrical practices and kit instructions, including cleaning and deburring.
4. Install the appropriate lug or connector onto the conductor, ensuring a secure and proper crimp.

Operating Instructions: Installation Procedure

The cold shrink technology simplifies installation by eliminating the need for heat. Follow these general steps, always referring to the detailed instructions included with your kit for specific dimensions and techniques.

1. Clean and Prepare: Thoroughly clean the prepared cable insulation and lug with an appropriate solvent and allow to dry.
2. Position Termination: Carefully slide the cold shrink termination tube over the prepared cable end and onto the lug. Ensure the termination is correctly aligned and positioned over the stress cone area.
3. Odstraňte jádro: Locate the plastic core inside the cold shrink tube. Begin unwinding the core from one end, pulling it out slowly and steadily. As the core is removed, the silicone rubber tube will shrink tightly onto the cable and lug, forming a seal.
4. Grounding (if applicable): Install any necessary grounding components (e.g., copper braid, constant force springs) as specified in the kit instructions.
5. Seal (if applicable): Apply any mastic sealing tapes or additional sealing materials as directed by the kit instructions to ensure a moisture-tight seal.
6. Kontrolovat: Visually inspect the installed termination to ensure it is fully shrunk, properly seated, and free from any defects or voids.

This kit is specifically designed for splicing and terminating electrical cables, providing insulation and environmental sealing for medium voltage aplikací.

Údržba

The 3M Cold Shrink QT-II Silicone Rubber Termination Kit is designed for long-term, maintenance-free operation once properly installed. Regular maintenance is generally not required for the termination itself.

• Pravidelná prohlídka: Periodically inspect the installed terminations for any signs of physical damage, cracking, or environmental degradation.
• Environmentální faktory: Ensure the termination area remains free from excessive moisture, dirt, or corrosive substances that could compromise its integrity over time.
• Čištění: If necessary, gently clean the exterior of the termination with a soft, damp tkanina. Vyhněte se používání agresivních chemikálií nebo abrazivních materiálů.

Odstraňování problémů

While cold shrink terminations are generally reliable, issues can arise from improper installation or environmental factors. Here are some common concerns:

• Incomplete Shrinkage: If the termination does not fully shrink, it may indicate that the plastic core was pulled too quickly or unevenly, or that the cable diameter is outside the specified range. Ensure slow, steady removal of the core.
• Voids or Gaps: Voids can occur if the cable preparation was not smooth or if the termination was not properly positioned. Re-installation may be necessary if voids compromise insulation.
• Poškození během instalace: Avoid sharp objects or excessive force that could puncture or tear the silicone rubber. If damaged, the termination must be replaced.
• Environmental Degradation: Over time, extreme UV exposure or chemical contamination can affect the material. Ensure proper environmental protection if installed in harsh conditions.

For persistent issues, consult a qualified electrician or contact 3M technical support.
