LV ABC
Low and Medium Voltage
LV-Aerial Bundled Conductor (LV ABC) System is an effective solution offered by Raychem which prevents theft by direct tapping, the most basic method of stealing electricity.
Raychem was one of the first to pioneer the connection, anchoring and suspension of low-voltage insulated overhead systems. Our continuous efforts in research and development have led to state-of-the-art product lines, that meet the demands of modern network design, operation and maintenance. Our products are successfully employed by utilities around the world including artic, desert and tropical climatic extremes. With Raychem’s piercing connectors, service lines can be connected to live lines with maximum safety to linemen.
- Total elimination of faults on LT lines
- Improved reliability
- Avoidance of theft by direct tapping
- Avoidance of overloading of Distribution transformers

LV ABC acessories
Anchor clamps for self-supporting LV-ABC lines
The clamps are designed to anchor self-supporting LV-ABC lines with 2 to 4 cores. The wedge type clamp is self-adjusting. Pilot wires or street lighting conductors are led alongside the clamp.
The insertion of conductors is facilitated by an integrated spring, which helps open the clamp. The version with movable arms in addition simplifies the installation
- Single M12 bolt and self-locking nut allow clamp to be fixed also to closed eye screws and brackets
- Short length of approx. 320 mm
- Exceeds requirements according to ESI 43-14 and VDE 0211 and in futureto CENELEC prEN 50483-2
- Clamp made of weather and UV light resistant glass fibre reinforced polymer and hot dip galvanized steel
Suspension clamps for self-supporting LV-ABC lines
The clamps are designed to suspend self supporting LV-ABC lines. They can be also used for LV-ABC lines with bare and insulated neutral messenger.
- Can be installed in straight direction and in line deviation angle up to 30°
- Tool free installation, equipped with wing nut
- Exceeds requirements according to ESI 43-14 and VDE 0211
- Made of weather and UV-light resistant elastomer and hot dip galvanized steel
- Fits to hooks and pigtails up to a diameter of 21 mm
- Operating load 2, 5 kN
Anchor clamps for LV-ABC lines with insulated neutral messenger
The clamps are designed to anchor LV-ABC lines with insulated neutral messenger. The clamp consists of an aluminium alloy cast body and self-adjusting plastic wedges which clamp the neutral messenger without damaging its insulation.
The flexible stainless steel bail protected by plastic wear-resistant saddle allows installations of up to 3 clamps on a bracket. The clamp and the bracket are available either separately or together as assembly.

- Tool free installation
- Not lose parts
- Exceeds requirements according to CENELEC prEN 50483-2 and NFC 33 041 and 042
- Clamp body made of corrosion resistant aluminium alloy, bail of stainless steel, wedges of weather and UV resistant polymer
- Universal fixing of bracket by 2 bolts M14 or stainless steel straps of 20 x 0,7 mm
- Bracket made of corrosion resistant aluminium alloy
Suspension clamps for LV-ABC lines with insulated neutral messenger
The clamps are designed to suspend LV-ABC lines with insulated neutral messengers. The neutral messenger is fixed by an adjustable grip device. A movable link allows longitudinal and transversal movement of the clamp body.
Standard clamp version ES is supplied with preinstalled bracket. The upper bulge of the bracket prevents the clamp from turning over the bracket. The clamps are also available without bracket (version PS) and with a fuse link (ESF). PS clamps are fixed to a pole by a pig tail hook or bracket.
- Tool free installation
- Not lose parts
- Clamp and link made of polymer giving an additional insulation between the cable and the pole
- Exceeds requirements according to CENELEC EN 50483-3 and NFC 33 040
- Clamp and movable link made of weather and UV-light resistant glass fiber reinforced polymer
- Universal fixing of bracket by 1 bolt M16 or 2 stainless steel straps of 20 x 0,7 mm
- Bracket made of corrosion resistant aluminium alloy
Wall mounted saddles and cable ties for LV-ABC lines
The wall mounted saddles are designed to install LV-ABC lines (self-supporting or insulated neutral messenger type) alongside walls and poles.
The LV-ABC cable is fixed to the saddle by a cable tie. A second cable can be installed on the same support by hanging it down from the bottom side with an additional cable tie.
- The body of saddles and the cable ties are made of weather and UV light resistant polymer material
- Width of cable ties 9 mm
- Black colour
- Halogen free and flame retarded
- Temperature ranges: operating –50 °C to +80 °C, installation –15 °C to +60 °C, max. allowed peak 120 °C
Service Anchoring clamps for armored and un-armored cables
The clamp is designed to anchor insulated service lines with 2 to 4 conductors. The clamp is composed of a body, 2 wedges and removable and adjustable bail.
- Tool free installation
- No loose parts
- Easy to open bails permits fixing to brackets and pigtails
- Bail lengths can be adjusted up to 220 mm in four steps
- Exceeds requirements according to NFC 33 042
- Clamps made of weather and UV-light resistant glass fiber reinforced polymer
- Adjustable link made of Stainless steel and hot dip galvanized steel
