Medium Voltage tree wire (Medium Voltage Covered Conductor) meets or exceeds the requirements of all international standards like ASTM,IEC,DIN,BS,AS,CSA,NFC,SS,etc. in addition, we also accept OEM service to meet your special request.
Application:
Medium Voltage Covered Conductors provide the effective solutions to prevent the revenue loss due to theft by direct tapping, tree faults and other problems associated with bare overhead conductors. Covered conductors have been tested across two conductors of 22kV for upto 300 hrs, after which the test was discontinued. This has proved the reliability and effectiveness of MVCC in preventing the system failure on account of transient faults created in system due to falling trees or branches.
Construction:
Covered conductors consist of stranded hard drawn aluminum conductors with either one, two or three extruded layers depending on the voltage rating. Covered conductors are available in black or gray depending on visual preference. In a Covered Aerial MV System (formerly called Spacer Cable), spacers hold three MV phase conductors in close approximation. The spacers are suspended from a high-strength messenger wire. Covered Aerial MV (CAMV) cable itself is a single aluminum conductor protected by a layer of track-resistant polyethylene.

Reliable Power Transmission for Overhead Utility Networks
The Pisen Cable Medium Voltage Covered Conductor is designed for reliable, long-distance power delivery in overhead distribution systems. It supports electrical cable infrastructure in rural, suburban, and forested areas where tree contact and harsh weather are common. Ideal for utility providers and energy companies, this wire and cable solution ensures consistent performance even under challenging environmental conditions, thanks to its high-durability insulation and UV-resistant construction. It reduces outages and enhances the security of the overhead cable system by minimizing short circuits and conductor clashing.
Weather-Resistant XLPE Insulation for Extended Service Life
Manufactured with cross-linked polyethylene (XLPE) insulation, this power cable delivers superior thermal resistance and electrical reliability. It meets or exceeds industry standards such as ASTM B231, ICEA S-66-524, and AEIC CS8, supporting nominal voltages from 15kV to 35kV. The conductor core consists of concentric stranded or compressed 1350-H19 aluminum, making it a robust and efficient electrical conductor. The rugged outer layer protects the electric wire from UV radiation and moisture, ensuring longevity and operational efficiency across all weather conditions.
Ideal for Tree Wire and Covered Line Installations
This covered conductor is best suited for covered line wire and tree wire configurations, offering a safer alternative to bare conductors in densely vegetated corridors. It is widely used in medium voltage overhead distribution, particularly where contact with trees or wildlife is expected. Engineers and network planners benefit from a reduced risk of faults, making this mv cable a practical solution for grid modernization efforts. It integrates seamlessly into industrial cable systems, promoting operational continuity and safety compliance in regulated environments.
Product Advantages
XLPE Insulation Enhances Thermal and Mechanical Stability
Unlike conventional insulation, the XLPE layer used in this electric wire offers improved dielectric strength and high-temperature tolerance. This enhances the conductor’s ability to withstand electrical load fluctuations without degradation. It is especially beneficial in medium voltage cable applications where reliability is crucial. The insulation structure also resists cracking and corrosion, reducing maintenance costs and ensuring long-term asset value in wire and cable systems exposed to external elements.
Reinforced Conductor Core Using 1350-H19 Aluminum
The conductor utilizes high-purity, hard-drawn 1350-H19 aluminum electrical wire, which provides a balance of strength and conductivity. This material selection reduces line losses while maintaining mechanical robustness, vital for tensioned overhead cable systems. Whether in single-phase or three-phase installations, this aac conductor design supports higher current loads with minimal sag. It's particularly effective in regions requiring corrosion-resistant and lightweight cables.
UV and Moisture Resistant Outer Layer for Harsh Conditions
With its black, weather-resistant outer sheath, this product is purpose-built for installation in humid, coastal, or high-UV exposure zones. The outer insulation safeguards the electrical cable from degradation due to solar radiation and environmental pollutants. This added durability ensures consistent current flow and mechanical integrity in abc cable and covered line wire applications, thereby reducing failure rates and increasing system uptime in utility-grade deployments.
Use Scenarios
Rural Utility Operators Managing Forested Grid Areas
Utility companies operating in forested or tree-dense regions benefit from this covered line wire, which minimizes power outages caused by foliage contact. Its robust medium voltage cable insulation design prevents arcing, making it ideal for overhead systems in storm-prone or mountainous terrains. Field technicians can deploy this wire cable with reduced need for trimming vegetation, enhancing operational efficiency while improving public safety.
Electrical Engineers Upgrading Suburban Grid Infrastructure
For suburban distribution grids undergoing modernization, this mv cable offers an efficient solution that meets modern safety codes. Engineers working on grid upgrades or substation expansions can rely on the product’s compatibility with standard hardware and its resilience in above-ground installations. Its reliable electrical conductor construction allows planners to extend service capacity while reducing risks linked to wildlife interference and line corrosion.
Renewable Energy Consultants Deploying Medium Voltage Lines
Renewable energy sites such as wind farms and solar parks require durable, weatherproof industrial cable systems for power transmission. This product provides reliable electric wire performance in overhead routing from energy generation points to substations. Consultants benefit from a high-efficiency aluminum cable core, which supports long-distance transmission without excessive voltage drop, making it a sustainable choice for low-loss grid integration.
