COTRAN PVDF175 tube is transparent, thin wall PVDF (polyvinylidene fluoride) heat shrink tube designed for electronic, automotive and military applications requiring protection and see-through inspection in aggressive environments.

Applications:

To provide oil resistance, void filling and sealing for oil-immersed cable termination and joints for heat shrink technology up to 36kV.

COTRAN spacer tape is extruded into two crossed threads that can then divert liquids, leading to its wide usage for casting resin joints in different applications, such as Low- and Medium Voltage, Cable Accessories and 2-component epoxy or PUR Cast Resins. It is engineered to build up voids in odd shaped splices and assures full resin coverage and forms a liquid tight mold.

COTRAN cast resin joint kits are reliable jointing solutions for intermediate connectors of wires and cables. The cast resins without filler are high quality, and fast setting resin for tough ambient conditions. Ideal for power cable accessories as insulation or as protective layer in case of MV joints. The products have the advantages of excellent waterproof performance, convenient installation, excellent electrical performance and long-term immersion in water.

The shear bolt connectors are intended for stranded and solid aluminum and copper cable, low voltage and medium voltage up to 36 kV.

They comprise cable areas 10-400 mm² even bigger for sector cable. There is also a screw sleeve for branches up to a total of 100 mm². The joint with the conductor is achieved by the screws in the connector or terminal being tightened to a predetermined torque.

1. The body of joint is made of imported silicone rubber with good quality, so it is with high strength, elasticity and tear resistance as well as excellent thermal

aging resistance.

2. The body of joint has integral pre-fabricate structure with high voltage shielded, stress cone and insulating injection pressed integration, so it has excellent properties and easy to test as well as install.

3. The body of joint is analized and computed optimization by finite element software, so it has more resonable field-intensity distribution and high insulation safety margin.

4. The body of insulating joint and straight through joint is the same, the d ifference is just the handling of shielding on-site installation, insulating joint with one side insulated and the rest shielded while staight through joint full shielded.

5. The joint has completely sealed structure with high mechanical strength and good sealing performance.

6. Joint protecting is made of insulating copper case with high-intensitive T2 copper, and the moulded high-density PE material of its external surface is used for insulation and anti-corrosion with good mechanical protection and permanent waterproof sealing performance, which ensure the joint to run safely and reliably in the long-term under harsh environment.In addition, it can equip glass fiber reinforced plastic protective box as a strengthen waterproof measure accordingly.

7. Special installer tools make the installation more convenient.
