Cable Test Terminations & Water Processing Unit

Haefely renowned in the HV world, is a leading supplier of Cable Test Termination Systems (CTTS). Our CTTS has earned the industry’s confidence and has gained an image as a first class product. Following our philosophy of continuous product improvement, we have upgraded the entire product line. The CTTS line is backed by our 100+ years of experience in HV testing. They make HV testing of cables fast and easy. Major highlights of the product line are very short peeling lengths for routine testing, interchangeable tubes with higher LI specification for impulse tests, SI specification and C/tanδ...

Benefits * Low Ownership cost as peeling length and prep time is short * One compact, integrated system covers AC, LI, SI, PD C/Tan Delta, Step test * Small foot print * 20% higher withstand voltage test possible than rated voltage * Special deionization system, minimal opex

CTT: Test Termination Principle Outer tube Inner tube Water outlet Water inlet C/tan δ testing point H.V. Cable Each termination – comprising inner- and outer-tubes and electrodes at the high and low voltage ends – is mounted on its own base frame with wheels. The aim of the CTT is to attain a linear voltage distribution along the tubes of the termination to avoid field enhancement and partial discharge on the surface. This is achieved by water with low conductivity. The water processing unit continuously regulates the conductivity of water so that it stays at the set value. It also has a heat...

Perfect Investment As a result of the new CTT design optimal peeling lengths and preparation times are achieved. Using these CTTs leads to measurable advantages during cable testing which save time and money for the user. The CTTs from Haefely are the most economical choice compared to other test terminations 2 terminations on separate trolleys 2 cable seal moulds Silicone compound for 4 seals Spare outer tube spare inner tube 5 kg silicone sealing compound Motorized Jacking C/tangent delta point Longer tubes for higher LI specificiation Adapters for WC 120 water conditioners Longer interchangeable...

Water Processing Unit Principle Meters: pressure, temp., flow, conductivity The water processing unit, WPU, regulates the conductivity of the water and serves as cooling system. Thermal losses, which are generated in the CTT during the cable test are dissipated in the WPU, to avoid an overheating of the water. The regulation of conductivity is very important to provide and ensure thermal stability of the system also during long term test. The WPU uses a deionizing resin to regulate conductivity. After the test is done, it also empties the tubes. External cooling water Outlet From cable termination...
