High Huality Performance Of Inline Closure

Date:24-03-2019

Inline Closure——Sealing Performance

Pressurized up to 100Kpa±5Kpa into the sealed FOSC,then put the FOSC into the water 15minutes.There are no air bubbles.Or there is no change of air pressure within 24 hours.

Inline Closure——Re-entry performance

Re-entry the FOSC 3 times as normal working condition,and pressurized up to 100Kpa±5Kpa into the sealed FOSC,then put the FOSC into the water 15minutes.There are no air bubbles.Or there is no change of air pressure within 24 hours.

Inline Closure——Mechanical Character

1.Tensile Test: The axial tensile strength should be not less than 800N,and there is not any crack.

2.Squeezing test:The FOSC can bear 2000N/m2 ,the lasting time is 1 minute.There is not any crack.

3.Impact test:The FOSC can bear 16N.M impact 3 times,there is not any crack.

4.Bending test:The link part of cables and FOSC can bear 150N bending strength.The bending angle is ±450 ,repeat 10 times,there is not any crack.

5.Torsion Test:The FOSC can bear 50N.m torsion.The torsion angle is ±90°,repear 10 times,there is not any crack.

Temperature Cycling Test

Pressurized up to 60KPa±5Kpa,the FOSC can bear temperature cycling from -40°C to +65°C.Put the sample to the high temperature surrounding 2 hours,then 2 hours at room temperature,then 2 hours at low temperature,last return to room temperature 2 hours ,repeat not less than 10 times cycling.The droping of the air pressure not more than 5Kpa.Put the sample into the warter for 15 minutes,there is not any bubbles.

Voltage Resistance

Put the sealed closure into the 1.5m deep water for 24h.15kv direct current between the metal parts of both ends or between the earth and metal parts,there is no puncture and no flying-arc.

Insulation Resistance

Put the sealed closure into the 1.5m deep water for 24h.The insulation resistance between the metal parts of both ends or between the earth and metal parts should be not less than 2×104MΩ

Competitive Advantage

Strictly enforce the ISO9001 quality management system, companies with good facilities and qualified human resources management to ensure product quality stability and excellent performance; and good after-sales service, to win the trust of customers, productsexported to Europe and the United States and Southeast Asian countries.
