GTL copper aluminum wire conduit is a tubular connecting component designed specifically for the connection of copper and aluminum wires (such as power cables and overhead wires). Through copper aluminum metallurgical bonding technology, the two ends are respectively adapted to copper and aluminum wires, which can avoid electrochemical corrosion caused by direct contact between copper and aluminum, and form a tight compression joint through the tubular structure to ensure high current and low impedance transmission. Widely used in scenarios such as distribution lines, overhead power transmission, and new energy cable docking, it is the core component for solving the straight connection of copper aluminum wires
The performance core of GTL copper aluminum junction tube lies in the stability of copper aluminum bonding and the reliability of tubular crimping. The structural design and production process directly determine the conductivity efficiency, corrosion resistance, and mechanical strength
The application scenarios of GTL copper aluminum junction tubes are highly concentrated in the field of power transmission and distribution where copper aluminum wires need to be connected in a straight line. The core includes:
Distribution line renovation:
Upgrading of old residential area lines: Connect the existing aluminum overhead wires (such as LGJ-50) with newly added copper cables (such as YJV-50), use GTL-50 wiring conduit to solve the transition problem of copper aluminum wires, and avoid excessive voltage drop of the lines caused by corrosion;
Rural power grid renovation: Adapt to the common aluminum wires in rural power grids and connect them with copper busbars in distribution rooms. The GTL-70 wiring conduit can withstand outdoor humid environments and ensure the stability of power supply in rural power grids.
In the field of overhead power transmission:
10kV/35kV overhead line: used for copper aluminum wire connection in line segmentation (such as connecting copper wire segments with aluminum wire segments), GTL-120 explosive welding type wiring tube, low impedance to meet the transmission of high current (≥ 1500A) of the line, and wind resistance to pendulum vibration;
Photovoltaic/wind power overhead collection line: connects the aluminum cable of the photovoltaic power station with the copper cable of the booster station. The GTL-185 wiring conduit has strong weather resistance and is suitable for outdoor high and low temperature environments (-40 ℃~80 ℃).
New energy cable docking:
Energy storage power station battery cluster cable: used for the connection between aluminum busbar cables and copper battery pole leads in energy storage systems. The GTL-25 junction tube has low impedance to meet the high current (≥ 300A) requirements for charging and discharging, avoiding heat generation and affecting battery performance;
Electric vehicle charging cable: Suitable for temporary connection between copper cables and aluminum cables of charging stations (such as emergency charging scenarios), the GTL-35 wiring conduit is compact in size and easy to crimp.

Automatic Closing Device for Low-Voltage Circuit Breakers Based on Time RelaysTo ensure safe and stable grid operation and prevent load current surges from damaging electrical equipment during power restoration, all loads connected to distribution transformers must be disconnected before energizing.Therefore, low-voltage circuit breakers are equipped with an undervoltage release function: when a transformer is de-energized due to maintenance or line faults, the loss of voltage on the low-voltage bus causes the branch circuit breaker to trip automatically.

Understanding the Difference and Applications of On-Delay and Off-Delay Time RelaysIn electrical and electronic engineering, time relays are crucial control components. Operating on electromagnetic or mechanical principles, they delay the closing or opening of contacts within control circuits. This time-delayed action enables circuits to automatically perform specific operations after a set interval. Based on their timing characteristics, time relays are primarily classified into two types: on-delay and off-delay.1. On-Delay Time RelayAn on-delay time relay does not respond imEcho09/16/2025 -
Marine Time Relay Setting and Common Fault TroubleshootingCommon Faults and Troubleshooting:(1) Over time, the adjustable potentiometer used to set the delay time may suffer wear of the carbon film or accumulate dust, leading to inaccurate timing. To address this, apply a small amount of electrical contact cleaner around the potentiometer shaft, then rotate the shaft back and forth to clean the internal contacts. If the potentiometer is severely worn, replace it promptly.(2) Damage or aging of transistors can alter the parameters of the timing circuit,Felix Spark09/16/2025 -

Why Regular Transformer Maintenance Matters: 5 Serious Consequences of Neglecting ItI. Allowable TemperatureWhen a transformer is in operation, its windings and iron core generate copper loss and iron loss. These losses are converted into heat energy, causing the temperature of the transformer's iron core and windings to rise. If the temperature exceeds the allowable value for a long time, the insulation will gradually lose its mechanical elasticity and age.The temperature of each part of the transformer during operation is different: the winding temperature is the highest, folRockwell09/12/2025 -
