The insulation-piercing clamp for insulated conductors (ENEL model) is intended to prepare insulated low-voltage conductors in distribution boards and transformer substations for short-circuiting and earthing. It is designed and manufactured according to ENEL technical specification EA 0138 RO.
The clamp body consists of two insulating, flame-retardant and weather-resistant parts. The piercing rod has an external 8 mm-diameter hole for connecting the phase clamps of the short-circuiting device. As it carries current between the cable and the short-circuiting device, it is made of tin-plated copper alloy. Fasteners are stainless steel.
