Alroc AMF5 55-160 tool removes the need for HV jointers to “glass” the outer conductive sheaths as the highly precision engineered cable jointing tool provides accurate stripping of HV and EHV cables in a motor controlled rather than manual process.

Safety Rules OK!
Pfisterer Connex 6S ready to plug in – the cable termination end is carefully protected and covered. This cable is situated inside a temperature controlled room and is “red-taped” to prevent unplanned entry.

“Great Safety is Great Business”
High voltage is high risk therefore worker safety is paramount at Allteck. Actually, it’s more than that – it is their number 1 core value.
According to OSHA, typical occupational hazards include :
- High voltage cable or power line contact
- Working at dangerous height
- Working in confined spaces
- Challenging weather conditions and terrain – urban and rural work locations
- Vehicle traffic
Correct PPE and fall arrest equipment are minimum safety requirements for the Lineman’s body. Most important is the “safety mindset” of the company – Allteck have a proud and proven track record in implementing the highest levels of safety standards.
Safety is at the heart of their company culture and reputation.
