630A 24kV Separable Premold Deadbreak Front Tee Cable Connectors

Structure:Fully shielded, insulated and a total safe to touch Material: EPDM Rubber OEM is available ISO9001:2008 Certificate

I. Application and Function: Seperable Premold Front Tee Cable Connector is designed to connect polymeric 12, 17.5 and 24 kV insulated cable to MV equipments equipped, such as transformers, switchgears, RMU etc. It can also be used to splice power cables by assembling multiple Tee connectors using Connecting Plugs.

II. Characteristics:

i. Fully insulated, fully sealed and fully screened structure, no require for operating distance

ii. Insulating layer between the Conductive insert and the Conductive jacket is injection molded, which ensured perfect insulating property.

iii.13 years experience and 100,000pcs performance experience

iv. Pass type test of authority

III. Size: Sections from 35 up to 500 mm²

IV. Material: The main material of the Cable Connectors is EPDM rubber.       

Characteristics of EPDM: Withstand the bad weather, anti-aging, perfect electric insulativity and anti chemical corrosion.

V. Rigorous, systematic Quality Control

i. Design and production quality system has been certified as being in conformity with the requirements of ISO 9001: 2008

ii. Each process has the quality testing work, the following process to check the before process work and record it which make the possibility to track the full manufacture.

iii. Each product should pass the strictly test of insulating resistance, AC withstand voltage, partial discharge and other electrical characteristic tests before leaving the factory.

iv. After milled, we will apply the vulka-meter to test the rubber’s properties, such as vulcanizing property, hardness etc. Different products should use rubber with different hardness.

v. Before applying the insulating rubber, the samples will be done withstand resistance test to ensure the correct of the applying rubber.

VI. Experience

13 years experience of Tee Shaped Cable Connector and more than 200,000 pcs have been used locally and abroad. The products occupied 32 provincial administrative areas and provided products for numbers of transnational corporationslocally. What’s more, they had been exported to Korea, Vietnam, India, Pakistan, Brazil etc.
