Ampact Wedge Connectors
We develop and manufacture Wedge Utility Connectors which are designed around an engineering principle which we call as ‘Wedge Pressure Technology’. Field proven for more than 40 years, Wedge Pressure Technology has formed the basis for a complete family of connectors that outperforms other conventional connectors, resulting in ‘lowest life cycle cost’. Wedge Connectors (Boltless Connectors) overcomes the physical and electrical limitations of traditional compression or bolted connectors resulting in low technical losses and efficient & consistent current flow.
Features:
- Designed specially to manage peak power transmission temperature up to 250 degrees
- Provides an efficient electrical connection for any type of power conductor combination
- Withstands severe electrical and mechanical stresses
- Easy installation without damage to conductors
- Easy removal of connector without damaging the conductors and are re-usable
Transformer is a vital component of a distribution system. It has to deliver Reliable Power in a safe & efficient manner. However, 8% of the transformers installed worldwide fail on account of improper connector systems.
A conventional connector system used for LV cable connection, deploys crimping and tightening of the bolts. Over a period of time, it leads to a loose electrical contacts which causes sparks and hot spots. The contact resistance is high which adds to the losses of ailing utilities. The weight of the connector causes mechanical strains on the bushing of the transformer, leading to oil leakages.
Raychem’s Trafo connector is engineered to keep the contact resistance low for the lifetime of the transformer. Its lighter & pretty simple to install as it uses the modern shear bolt technology, hence avoiding the skill & tool dependent crimping methodology. It significantly increases the reliability of the transformer.
Features and Benefits:
- Simple and easy Installation
- Light weight connecting system
- No tools required
- Low resistance (I2R) losses
- Maintenance free
- Reliable & Insulated connection

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.
The major advantages of LV ABC are:
- Total elimination of faults on LT lines
- Improved reliability
- Avoidance of theft by direct tapping
- Avoidance of overloading of Distribution transformers
