COMPAQ 11KV 3C*300SQMM STRAIGHT THROUGH JOINT KIT

About COMPAQ 11KV 3C*300SQMM STRAIGHT THROUGH JOINT KIT

What is a 11 kV 3C 300 sq mm Straight-Through Joint Kit and Where It's Used

• A straight-through joint kit is used to splice/joint two 11 kV 3-core cables (with conductor size 300 sq mm) so that the joint behaves electrically and mechanically like a continuous cable. This is commonly needed when you want to extend cable length, repair a damaged cable section, or connect cable runs in underground ducts / cable trenches. pvsmart.in+2parkerelectronics.in+2

• It is suitable for polymeric-insulated (XLPE / EPR / similar) 3-core cables of 300 sq mm size used in medium-voltage distribution networks. ETS Cable Components+2Micraa+2

• The straight-through means the cores remain in-line (i.e. cable-in to cable-out), not branching or termination so its ideal for underground, ducted or direct-buried cable splices where through-continuity is required. Axis India+1

Typical Components Inside the Kit

A standard heat-shrink (or cold-shrink) 11 kV straight-through joint kit for 3C 300 sq mm will typically include the following: pvsmart.in+3parkerelectronics.in+3MSEDCL+3

Many kits are designed so that after proper application (heat-shrinking or cold-shrink depending on kit), the joint becomes as close as possible to original cable in insulation thickness, dielectric performance, mechanical strength, and environmental sealing. parkerelectronics.in+2pvsmart.in+2

Key Features & Benefits of Such a Joint Kit

• Voltage compatibility: Rated for 11 kV cables suitable for medium-voltage distribution networks, underground cable systems, industrial and utility supply. pvsmart.in+1

• Cable size support: Supports 3-core 300 sq mm (and often a range, e.g. 240 300 or 240 400 sq mm depending on kit) matching common cable specs used in MV networks. ETS Cable Components+2zamcables.com+2

• Full insulation & shielding restoration: Stress-control layers + insulation + metallic screen / shield continuity via copper braid/mesh restore full electrical integrity essential for safety and performance. parkerelectronics.in+2Axis India+2

• Moisture and mechanical protection: Outer jacket / sheath + sealing materials make the joint resistant to moisture ingress, soil, abrasion important for underground or duct installations. parkerelectronics.in+2pvsmart.in+2

• Ease of installation (with correct technique): Heat-shrink (or cold-shrink) sleeves and modular components simplify installation compared to old-style mastic or resin joints; reduces workmanship errors. Axis India+2buyelectric.com+2

• Flexibility: Suitable for both new installations and repair/splicing of existing cable runs useful in cable route extensions or maintenance. pvsmart.in+2Axis India+2

Important Considerations / What to Check Before Use

When specifying or installing a 11 kV 3C 300 sq mm Straight-Through Joint Kit, ensure:

• The cable insulation type (XLPE / polymeric / screened) matches the kits design. Kits meant for XLPE / polymeric may not suit older PILC or other cable types. ETS Cable Components+2pvsmart.in+2

• Use proper connectors / lugs sized for 300 sq mm conductor (copper or aluminium as per cable) to ensure current-carrying capacity and mechanical strength. Bharat Heavy Electricals Limited+1

• Ensure the screen / armour continuity and earthing is properly restored using copper braid/mesh, earth-clamp, etc. This is essential for safety and fault-clearing. parkerelectronics.in+2Bharat Heavy Electricals Limited+2

• Installation must follow correct procedure stress-tube placement, insulation, sealing, outer sheath application; curing procedure (heat shrink or cold-shrink) must be properly executed. Poor installation can lead to insulation failure or moisture ingress. Axis India+2pvsmart.in+2

• Joint must be carefully tested / inspected after installation (insulation resistance, screening continuity, mechanical integrity) before energizing cable. Many supply specifications for joint kits require type-test certificates per relevant standard (e.g. for 11 kV straight-through joints). Bharat Heavy Electricals Limited+2techbaniya.com+2

Applicability for Voltmen Energy Projects

Given that your company deals with supply & distribution infrastructure (MV/HT cables, possibly in solar-linked or power distribution projects), a 11 kV 3-core 300 sq mm straight-through joint kit is quite relevant when:

• You need to extend or repair existing 11 kV cable runs underground or in ducts.

• You are deploying new 11 kV cable runs and need reliable inline joints (e.g. in long feeder cables, underground runs, etc.).

• You require robust, long-term, moisture-sealed, screened jointing for reliability under Indian environmental conditions (moisture, dust, etc.).

• You aim for compliance with standard specifications / utility requirements (insulation integrity, screen-continuity, mechanical protection, type-tested kits) in your tenders and documentation.

Superior Cable Compatibility

This kit is specifically compatible with 3 Core x 300 sqmm XLPE or EPR cables, supporting medium voltage power transmission at 11 kV. Its robust design caters to multiple industry needs, ensuring a reliable connection between cables of matching specifications.


Field-Friendly Installation

COMPAQ's straight through joint kit features a pre-fabricated design that makes onsite installation straightforward. It requires only a standard heat gun, with comprehensive kit contents and clear jointing instructions, enabling smooth and efficient field operations.


Reliability in Harsh Environments

Designed for demanding conditions, the kit's IP68-rated joint area safeguards against water and dust ingress. Additionally, its UV-resistant, weatherproof, and flame-retardant outer coatings ensure longevity even under extreme weather or outdoor exposure.
