INSULATION PIERCING CONNECTOR FOR BARE MAIN LINE RBB N AlCu 10-150mm²

MAREL Insulated connector for bare main line RBB N AlCu 10-150mm² is designed to install a surge arrester directly onto non-insulated overhead ACSR or copper power distribution lines. It is allowed to use the connector only with a surge arrester. It is not allowed to use the connector without a surge arrester.
The contacts are protected with electrical contact grease. When tightening the shear-off nut of MAREL Insulated connector for bare main line RBB N AlCu 10-150mm2 the contact pads fit well onto non-insulated overhead ACSR or copper conductor and makea perfect contact, thanks to the large contact surface. The contact plates are made of electrolytic sheet of excellent conductivity and very high mechanical strength. Therefore, the electrical contact is very reliable even on extremely low temperatures.
Tightening of MAREL Insulated connector for bare main line RBB N AlCu 10-150mm² is done until mechanical damage of shear-off nut occurs.
Additional tightening is allowed up to maximum mechanical load, maximum 1.5 circle from the moment of damage of shear-off nut.
Installation under voltage is possible but it is necessary to use adequate protective equipment.
MAREL Insulated connector for bare main line RBB N is designed in such a way that it enables fast, easy and reliable installation regardless of outdoor temperature.
The housing of the connector is made of Polyamide PA 6.6 (30-50% glass fiber reinforced), resistant to UV rays, weather conditions, temperature changes and aging.
MAREL Insulated Connector for bare main line:

• does not contain parts which could fall off during installation;
• can be used/installed only once;
• has an anti-rotation device (ARD), which enables easy and proper installation because it doesn't allow rotation of upper and lower part of the connector around its axis, which results in easy and deep penetration of contact plates through insulation of branch conductor

Installation wrench: 13
Dismantling wrench: 17
Wrench to hold the lower part during installation: 24
