Compression H Tap Connector
Compression H Tap Connectors are electrical connectors used for joining conductors. They are H-shaped devices made of aluminum or copper. These connectors have two grooves: A (larger) for the main conductor and B (smaller) for the tap conductor. Compression H Tap Connectors are suitable for aluminum-to-aluminum, aluminum-to-copper, and copper-to-copper connections. They are commonly used in overhead power distribution systems.
Compression H Tap Connectors serve multiple functions, including tapping, parallel connections, and two-way splicing. They are installed using compression tools and dies. The connectors work with various conductor types, such as ACSR, AAC, AAAC, and copper conductors. Compression H Tap Connectors are designed for permanent installations and provide reliable, low-resistance connections.
Features of Compression H Tap Connectors:
• Pre-filled with oxide inhibitor for corrosion resistance
• Compatible with standard compression tools and dies
• Made of high-quality aluminum alloy or copper
• Suitable for a wide range of conductor sizes
• Weather and water-resistant
• Color-coded for easy installation and identification

Frequently Asked Questions (FAQ)
What are H-tap connectors used for?
Compression H-tap connectors are designed for service dropping, primary and secondary tapping, and grounding installations. They work with various conductor combinations including aluminum-to-aluminum and aluminum-to-copper connections, making them versatile for electrical field applications.
What materials are H-tap connectors made from?
H-tap connectors are manufactured from 1350 aluminum alloy with pre-filled oxide inhibitor in the wire grooves. The oxide inhibitor is held captive in the rib/connection area to prevent corrosion and oxidation, maximizing the product’s service life.
What are the key features of H-tap connectors?
They feature a field-proven ribbed design for superior conductor contact, fold-in tabs for positive tool interlock, and pre-filled oxide inhibitor. The surface includes model numbers, matching die information, AB groove identification, and applicable cable size markings.
What tools are needed for installation?
Installation requires either a manual crimper or a hydraulic crimping tool with matching dies. The dies must match the color code or die index number engraved on the H-tap connector. Standard compression tools and dies can install all sizes.
How do you prepare conductors for installation?
Strip the cables carefully using a cable stripper, avoiding nicking strands. For aluminum conductors, brush the stripped portion with a stainless steel wire brush to remove oxide film, then apply oxide inhibitor compound. Never install more conductors than specified.
What standards do H-tap connectors meet?
H-tap connectors pass the requirements of ANSI C119.4 standard. They are designed for non-tension wire connections and are suitable for low, middle, and high voltage applications, ranging from 6 Sol. to 4/0 ACSR.
