About COMPAQ 33KV 3C*300SQMM STRAIGHT THROUGH JOINT KIT

What is a 33 kV 3C 300 sq mm Straight-Through Joint Kit and Where Its Used

A straight-through joint kit is used to join/splice two medium-voltage cables here, 3-core cable with 300 sq mm conductor so that the combined cable can continue with full insulation, screening/shield continuity, mechanical protection, and safety. Power and Cables+2Axis India+2
Designed for 33 kV (medium-voltage / HT) cable circuits. Useful in underground ducts, cable trenches, junction boxes, or other cable-containment systems. Power and Cables+2Optcl+2
Suitable for XLPE-insulated (or polymeric) or PILC-insulated 3-core cables of 300 sq mm cross-section. Power and Cables+2Power and Cables+2

Typical Components Inside the Kit

Based on standard heat-shrink straight-through 33 kV joint kits (as offered by major manufacturers / suppliers) a 3C 300 sq mm joint kit generally includes: Axis India+2Power and Cables+2

Component / Material	Purpose / Function
Heat-shrinkable stress-control tubing & mastic (one per core)	Manages electrical stress at cable-insulation cut ends when jointing prevents partial discharge and ensures dielectric integrity. Axis India+1
Heat-shrinkable insulating tubing / semiconducting tubing (per core)	Provides re-insulation and re-shielding over the spliced conductors after connector application. parkerelectronics.in+2Power and Cables+2
Tinned-copper mesh and copper braid / copper screening wrap	To restore metallic screen/shield continuity across joint necessary for screened or armoured cables for earthing / shielding. parkerelectronics.in+2Power and Cables+2
Outer protective sleeve / abrasion-resistant jacket / re-jacketing outer wrap	Provides mechanical protection, moisture sealing, environmental sealing especially for buried ducts / direct burial / harsh conditions. Power and Cables+2jpsassociates.net+2
Connectors / mechanical lugs / crimp/solderless connectors (compatible with 300 sq mm conductors)	To join conductors of the two cables securely to ensure electrical continuity and mechanical integrity. Power and Cables+1
Installation accessories: mastic/sealing compounds, tapes, cleaning materials, instructions	For proper preparation of cable ends, sealing voids, ensuring moisture-proof and stress-controlled jointing. Axis India+1

Key Features & Benefits

Voltage rating: 33 kV medium-voltage suitable for HT distribution networks in substations, underground cable trenches, industrial / infrastructure power distribution. Power and Cables+2Optcl+2
Cable compatibility: 3-core, 300 sq mm XLPE or PILC cables common in HT power distribution. Power and Cables+1
Insulation & stress control: Heat-shrink stress-control and insulating/semi-conductive layers restore insulation continuity and properly control electrical stress over the joint reducing risks of partial discharge, flashover or insulation failure. Axis India+2indogermanpower.com+2
Screen/shield continuity & earthing: Copper braid/mesh and shielding materials ensure that metallic screen or armour (if cable is screened/armoured) remains continuous and earthed vital for safety and electromagnetic shielding. Power and Cables+2indogermanpower.com+2
Mechanical protection & environmental sealing: Outer protective sleeve plus sealing materials make the joint robust against mechanical stress, moisture ingress, chemical exposure, suitable for underground or ducted applications. Power and Cables+2jpsassociates.net+2
Ease of installation (for trained installers): Heat-shrink technology and modular kit components help simplify jointing process compared to bespoke/manual methods though proper procedure must be followed. indogermanpower.com+1

Important Considerations / What to Verify Before Use

Confirm the cable insulation type (XLPE or PILC) and ensure kit is compatible with that insulation type. Some kits may be optimized for polymeric XLPE, others for paper-insulated lead-covered (PILC) cables. Power and Cables+1
Use the correct connectors / lugs compatible with conductor material and cross-section (300 sq mm). Incorrect connectors may compromise electrical/mechanical continuity.
Ensure proper installation procedure cable end preparation, cleaning, correct placement of stress tubes, copper braid, insulation layers, outer jacket, and sealing else joint reliability and dielectric strength may degrade.
After jointing ensure shield/screen continuity and proper earthing (if cable is screened or armoured) to maintain safety standards.
Use kit per standards / specifications for 33 kV cable joints (insulation, stress control, sealing, mechanical protection).
