In modern low-voltage overhead power distribution and utility renovation projects, reliable LV IPC connector play a decisive role for safe cable tapping, stable electrical contact and long-term outdoor anti-corrosion performance. Insulation Piercing Connectors are widely adopted for LV-ABC aerial bundled cable service tap-offs, thanks to tool-free stripping installation, controlled shear-bolt torque and weather-resistant properties. Many installers, distributors and EPC contractors are seeking reliable TTD151F analog insulation piercing connectors for general-purpose overhead tapping assignments. Jera Line ZOP-22N(LX) insulation piercing connector is a robust upgraded tapping solution engineered for overhead network construction and mixed-conductor grid renovation tasks. This blog walks through product definition, technical parameters, core features, real-world application scenarios and manufacturer advantages for global buyers.
ZOP-22N(LX) is Jera-Line self-developed single-bolt 1 kV LV IPC connector, also known as IPC piercing clamp, designed for overhead LV-ABC cable branch connections during overhead electrical line construction. It acts as a high-performance functional analog for widely-referenced TTD151F model, very popular within power utility, municipal street-light and telecommunication projects.
Its key working advantage lies in dual compatibility for both insulated and bare copper or aluminium conductors, covering main cable 10-95 mm² and tap cable 1.5-70 mm², wider coverage than conventional TTD151F reference. The connector adopts stainless-steel shear-head torque bolt, tin-plated bimetallic piercing teeth and UV-stabilized glass-filled nylon housing. Installers only torque the bolt until head shears off; bimetallic teeth pierce cable insulation and build stable metal-to-metal contact. Live-line hot installation is supported without power cut, greatly improving working efficiency for field electricians during pole-mount maintenance and retrofit.
Produced under strict in-house material control, critical raw-material batches including bimetallic teeth alloy, nylon housing granules and stainless-steel bolts are inspected before mass production. Raw-material composition verification avoids unstable contact performance or premature housing cracking caused by unqualified mixed-batch raw materials. It delivers stable electrical contact and decent anti-oxidation performance for long-term outdoor exposure, resisting atmospheric oxidation, UV radiation and normal temperature fluctuations in open-air conditions.
When installed correctly following installation manual, installers achieve rigid, consistent cable tapping without cable stripping, welding or complex pre-processing operations. The whole installation process can be completed with basic hand-operated tools, ideal for rapid field assembly, especially for pole-mount retrofitting and maintenance work.
As an upgraded functional alternative to TTD151F, it fully covers TTD151F insulated-cable application scope, meanwhile adds bare-conductor connection capability. Nevertheless, users should be aware of its application limits: when tender documents explicitly specify original TTD-series part number, ZOP-22N(LX) cannot be used as direct drop-in replacement due to commercial tender constraints. This product fills the market demand for high-quality IPC analog hardware for grid-renovation projects mixing old bare-wire sections and new ABC cables, helping distributors and EPC contractors optimise spare-part inventory while maintaining required electrical safety standards.
LV IPC connector ZOP-22N(LX) for insulated and bare cables is manufactured and Research and Design (R&D) by Jera Line, a direct factory location in China. The bare piercing connector consists of the following main parts:
Insulated and bare cable Insulation Piercing Connector ZOP-22N(LX) has passed regular routine test by Jera Line factory laboratory according to EN-50483:4 standard. The test scopes are as follows:
a) Visual examination
b) Dimensional and material verification
c) Test for permanent marking
d) Connector bolt tightening test
e) Shear head function test
f) Dielectrical voltage test in water
Jera-Line ZOP-22N(LX) is designed for wide-range cable tapping tasks where stable electrical contact and outdoor anti-ageing performance are essential. Its expanded conductor-range capability makes it suitable for multiple installation environments:
Selecting reliable insulation piercing connectors is essential to secure stable cable tapping and long service life for overhead power-distribution, municipal and telecommunication projects. As one of the most commonly-used overhead tapping hardware on-site, insulation piercing connectors bear continuous wind vibration, temperature cycling, atmospheric oxidation and environmental erosion throughout its service cycle.
Inferior-quality IPC products may suffer unstable contact resistance, bimetallic corrosion or premature housing cracking under outdoor exposure and cause hidden project risks such as power-supply failure, cable overheating and network breakdown. Such failures will trigger unnecessary maintenance costs, unplanned power outages and even potential safety hazards for public utility networks. Therefore, contractors and distributors should not only focus on upfront purchase cost, but also pay close attention to raw-material composition, full-standard test data and real-world outdoor performance when choosing IPC analog products.
Jera-Line ZOP-22N(LX), as a qualified TTD151F functional analog, provides certified, high-strength insulation-piercing hardware matching global utility-market requirements. Strict raw-material inspection and batch-by-batch lab testing according to EN-50483-4 Class A2 guarantee stable electrical performance and anti-ageing capability for long-term field deployment.
Together with matching installation hand tools, it forms a complete, easy-deploy tapping solution for overhead-line and outdoor-construction scenarios. This all-in-one hardware kit helps installers cut down preparation work on-site, shorten installation hours and lower overall project labour costs.
For different tender constraints and site-conductor conditions, our technical team can also offer professional suggestions on model-selection, reminding customers that ZOP-22N(LX) cannot replace original TTD151F when tender documents lock original part number. Whether you require product datasheets, pre-order samples, technical parameter confirmation or formal project quotation, please feel free to get in touch with our sales team.
