Program Overview
Most cable accessory failures trace back to preparation: a nicked insulation surface, a semiconductive screen cut too short, or heat applied unevenly during shrinking. This hands-on program trains installers to prepare and assemble Raychem low-voltage and high-voltage cable accessories to the manufacturer's installation instructions, consistently and safely.
The course begins with the product range and the role of each component: stress control, insulation, screen continuity and outer sealing. Participants then learn to identify cable screens and insulation types, select and use the correct tools, and complete joints on real cable samples. Every installation is checked against the instruction sheet, with instructors highlighting the critical dimensions and common errors that lead to partial discharge and premature failure. The result is an installer who works to the instruction sheet every time, not from memory.
Learning Outcomes
- Identify Raychem LV and HV joint and termination components and explain the function of each
- Recognize copper-wire, copper-tape and armored screen constructions and XLPE, EPR and PVC insulations
- Select, inspect and use cable preparation tools and gas torches safely
- Prepare cables to the dimensions specified in the manufacturer's instructions
- Install LV and HV straight joints with correct stress control, screen continuity and sealing
- Apply OSHA 29 CFR 1910.269 safe work practices during cable accessory installation
Program Modules
- Product Overview — the Raychem heat-shrink and cold-applied range for LV and HV networks and how components are matched to cable sizes
- Cable Accessories and Tools — stripping tools, semicon removal tools, torches, abrasives and cleaning materials, with inspection before use
- Cable Construction Familiarization — conductor, insulation, semiconductive layers, metallic screens and armor across common LV and HV cables
- Cable Preparation Techniques — measured stripping, screen termination, surface finishing and cleaning to avoid voids and contamination
- Heat-Shrink Application Practice — torch control, shrink sequence and recognizing correct recovery
- Installation of Cable Joints — complete LV and HV straight joints on cable samples, with dimensional checks and final inspection

Assessment & Certification
Assessment combines a written examination on cable construction, accessory components and safe installation practice with a practical assessment in which each participant prepares a cable and installs a complete joint that is inspected against the manufacturer's dimensional and workmanship checkpoints. Practical sessions take place at ASEEE-approved training centers, using calibrated equipment and realistic work scenarios under the supervision of a qualified assessor.
Participants who meet the competency criteria receive an ASEEE competency certificate carrying a unique certificate ID that employers and clients can verify online through Certificate Check. ASEEE recommends recertification every 3 years to keep skills aligned with current practice and revised standards.
