The TG4-12Q 110-180 Bushing Tube is an essential component in high-voltage switchgear systems, facilitating the safe and efficient passage of conductors through grounded barriers. Manufactured from high-quality epoxy resin, this bushing tube offers superior insulation properties, mechanical strength, and resistance to environmental factors.
The bushing tube is constructed from epoxy resin, known for its excellent dielectric strength and resistance to electrical breakdown. This material ensures reliable insulation performance under high-voltage conditions. The tube's design incorporates an inner cylinder, outer cylinder, insulating sleeve, support ring, and support bucket, providing robust mechanical support and protection against external stresses.
The TG4-12Q bushing tube is designed to withstand power frequency test voltages of 42kV for 5 minutes and lightning impulse voltages of 75kV, ensuring safe operation in high-voltage environments. The temperature of the lead-out terminal does not exceed 65°C under rated current conditions, indicating efficient heat dissipation and thermal stability.
The bushing tube is suitable for installation at altitudes up to 1000 meters and can operate in ambient temperatures ranging from -10°C to +40°C. It is designed to function in environments with relative humidity up to 95% at 20°C, making it adaptable to various climatic conditions. The absence of corrosive gases, vapors, or dust ensures the longevity and reliability of the bushing tube.
Operation condition:
1. Altitude: ≤ 1000m
2. Ambient temperature: +40 to -10°C
3.Relative humidity shall not be more than 95% at +20°C ambient temperature.
4. No gas, wapor or dust that may severely affect the insulation of contact box, no explosive or corrosive substance.
Technical requirements:
1.Coper contact to earth shall withstand power frequency test voltage (effective value) of 42kV for 5-minute and lightning impulse vpltage (peak value) of 75kV
2.Temperature of lead-out terminal shall not bemore than 65°C if the contact box is used for long time in rated current condition.
