TTD151F weatherproof UV black thermoplastic insulation piercing connector

SMICO TTD151F Insulation Piercing Connectors are made for service connections. The blades of the Service Insulation Piercing Connector are made of tin-plated copper or aluminium alloy allowing connections to aluminium and/or copper stranded conductors. These bodies are made of plastic with fiberglass allowing high resistance to its environment but also offering superior mechanical properties. A single torque control nut draws the two parts of the connector together and shears off when the teeth have pierced the insulation and made contact with the conductor strands.Ease of installation has been combined with excellent mechanical, electrical and environmental characteristics to provide a connector capable of terminating aluminium or copper stranded conductors. All of our insulation piercing connectors are designed and tested to fit the majority types of cables made in accordance with the European Standard HD 626, regardless of whether cables are insulated with XLPE, PE or PVC. The products are tested according to national specifications such as NFC 33 020, ANSI C119.5 and the European standard EN 50483-4. 

These standards include tests to verify reliable operation even in the harshest environments:

• Designed for installation from –20 °C up to +50 °C
• No limitation of mechanical loads for main and branch conductors
• Shear head forces are adapted to the required contact forces for each application (main, service, lightning)
• Voltage withstand to 6 kV in a 30 cm water bath
• No change in contact resistance and temperature after overloads and load cycling
• Voltage withstand to 6 kV in metallic balls after heavy weathering exposure (UV-light, humidity and temperature cycling)
• Corrosion resistance of the metal parts has been proven in the salt fog chamber and wet SO₂ gas chamber

• Range-taking
• Suitable for XLPE, PE or PVC conductors
• Waterproof
• Captive and flexible end caps
• All components are solid and fixed in place
• Equipped with shear head to ensure a reliable tightening torque
• Operating temperature -55°C to +55°C
• Installation temperature -20°C to +55°C
• Can be installed on energized main if not under load

01.What is a mechanical cable lug?

A mechanical lug is a heavy-duty electrical connector that uses screws or bolts to secure a conductor, rather than requiring specialized crimping tools. They are designed for easy installation in the field and are often used for larger cables in electrical and construction applications.

02.Is the clamp easy to install in the field?

Yes, the clamp is designed for easy installation, which can save time and reduce the need for specialized tools or extensive training.

03.Can the clamp accommodate different cable sizes?

Yes, it is designed to accommodate cable sizes ranging from 15 to 95mm², offering versatility for various cable specifications.

04.What materials are used in the construction of the High Electric Power ABC Accessories Tension Clamp?

The clamp is made from high-quality materials such as PA66 (a type of nylon) and aluminum alloy, which provide a combination of strength, durability, and resistance to weather and aging.

05.How to select cable lug size?

Selecting the correct lug size depends entirely on matching its rated conductor range to the precise cross-sectional area of the copper cable.

06.How does a mechanical lug work?

Lugs are crimped or bolted to the end of a wire, creating a secure connection to a terminal or bus bar. They often feature a mechanical set screw or compression mechanism for a reliable and durable attachment. Splices are connectors designed to join two or more wires together, ensuring electrical continuity.

07.Are SMICO Dead End Clamps reusable?

No. They are designed for single use to ensure consistent clamping force, insulation protection, and long-term reliability under mechanical and environmental stress.

08.What are the key features of SMICO Dead End Clamps?

• Corrosion-resistant aluminum alloy body

• Pre-assembled, ready-to-install design

• Operating temperature range: -20°C to 90°C

• Applicable Conductor Cross-Section: 16 mm² – 150 mm²

09.Do SMICO Dead End Clamps come with third-party test reports?

Yes. All SMICO Dead End Clamps are supported by independent third-party test reports, verifying compliance with relevant performance, safety, and durability standards.

10. What standards do SMICO Dead End Clamps comply with?

SMICO Dead End Clamps are manufactured in compliance with the international standard NFC33-042,EN50483-3, ensuring safety and operational performance.
