Product Advantages
35kV T-type bushing has many advantages :
It can effectively isolate the live parts, prevent the operator from electric shock, ensure the safety of personnel, and avoid short circuit, discharge and other faults caused by accidental contact, and ensure the normal operation of the equipment.
Prevent dust, moisture, etc. from entering the interior of the solid-sealed pole, reduce its impact on the insulation performance of the equipment, and prevent insulation degradation, flashover and other problems caused by moisture and dust accumulation.
It plays a mechanical protection role for the contact arm and other components of the solid-sealed pole, reduces the damage to the components caused by external force impact, friction, etc., and extends the service life of the equipment.
It uses materials with high insulation strength such as silicone rubber and EVA resin, which can withstand electric field strength of 35 kV and above, has good dielectric properties, and can reduce the risk of leakage and breakdown.
It has anti-ultraviolet, anti-ozone, anti-oxidation and other properties. It is not easy to age, crack, harden or soften under long-term outdoor or harsh environmental conditions, and can maintain stable performance.
It has a soft texture, good elasticity and flexibility, is easy to install, can fit the shape of the sealed pole tightly, and can deform without breaking due to thermal expansion and contraction or mechanical vibration during equipment operation.
Product Applications
35kV T-type bushing is Widely used in 35kV fixed circuit breaker and special trolley.
