Initially developed by a request from a domestic refinery in 1990. From 2009 onwards, users have been extended to customers in Russia, USA, Middle East. The service life goes three to four years at the site. Our two decade’s experience has enabled us to enhance their structure and function with the helps of kind users.

Tail Cable Length in mm note

  • - specific gravity 2.16~2.17
  • - tensile strength 35 MPa
  • - elongation 350%
  • - DBV 80 and over kV/mm
  • - Best PTFE from Dyneon and Daikin is employed for this use.
  • - A Strong Sealing System : Thread seal system shows excellent sealing effect under 25 MPa hydrostatic pressure test.
  • - A smoothly finished PTFE surface with 0.2µm roughness minimizes dirt’s adhering, which controls surface tracking at a minimum.
  • - Products are securely examined piece by piece by an experienced inspector. All entrance bushing undergo 10Mpa’s Hydrostatic Leakage Test and 38KV’s Dielectric Test.
  • - Prompt Delivery : bushings can be delivered within 4 weeks from order date with a small lot of 3 pieces.
  • - The customer’s own design can be corresponded.
  • - This item is a sensitive one, we are willing to help you with our installation, maintenance, handlings at the field and other services.
  • Lead Cable failure comes from a series of following procedures, corona discharge between cable and conduit housing – degradation of insulation oil and PTFE film on cable – arc discharge – cable break and fire. To control corona discharge, insulation oil needs to be kept clean by periodic inspection and have cable housing smooth inner surface to be free of scratch and remained arc mark. Make sure that cable housing need be made of a seamless tube, no welded one.
